Oops read your post too fast. I was thinking steering wheel position sensor, not steering wheel lock sensor.

Typically, if you KOEO and the fans blast away, the CEL light will NOT be illuminated. This indicates that a critical harness or sensor is not connected or bad. a fuse is blown, or you have a short (which probably caused a fuse to blow).

After doing this basic test, it's time to bring in someone with a Consult III, which will immediately uncover the problem.

With the batt. just conected the fans are blasting, head lights turn on but pass side markers dont work. Now since I pluged the steering lock sensor back in the car will turn on all the way but not start or even act like it wants to, and it wont turn off you have to pull the batt. cable. When I worked at Infinity it was not a big deal to scan it, but now I know the first thing they will say is that I need to put all the stock crap back in. I need to be there to work with the tech and I dont know how that is going to work out.

Sharif@Forged 03-05-2010 08:13 AM

Key off and battery connected and u get all that?? Call me today later in the day and I can Try to help over the phone.

Fathead 03-05-2010 09:51 PM

a good news / bad news story at this point...

Junior (fathead) is right, the car looks ready and unbelievably well prepared down to a very detailed level. Some finishing touches on the interior as well I think all will appreciate. Wing looks terrific - went with an 8" instead of 10" lift given availability of part but I like it at this height, so won't be changing that. Splitter is the best I've seen, hoping it isn't too well hooked up and takes out frame when I inevitably make contact!

Bad news is unfortunately after lots of experimentation, we were unable to get the car started. Sharif, if you are willing to this weekend, Junior would like to touch base with you. Believe he left you his number on your vmail. We are likely to find a friendly dealer in town this weekend and see if they are willing to hook up a Consult III and at least diagnose. Still getting same symptoms of:

- KOEO
- and headlights come on, radiator fans on
- fuel pump not starting and fuel showing on panel as 'empty' / 'zero range'
- also we found out by hooking up a known working OBD2 reader that there is no power / signal coming out of the OBD2 port... hoping this tells us somethign
- we checked all fuses everywhere and while we replaced one small 10amp fuse in the kick panel, there were no other blown fuses and replacing the 10a didn't do anything (not sure which it was)
- we checked all wiring, everything is connected solidly

Possibly, we blew up some circuit while working on the car last few months... who knows at this point.

I'm disappointed about this weekend, but tempered by the fact that the car is looking great across all other dimensions.

T

travisjb 03-05-2010 10:23 PM

junior, by the way, when you get a chance, can you please post which 10a fuse it was... just count how many rows and columns over from top left and I'll look it up on the service manual... that might be a clue about what's going on... thanks

travisjb 03-08-2010 10:56 PM

Car is at a local dealer, right now we are thinking the problem is serious b/c the check engine light is on with key on... which according to my better informed colleagues means that all is good with wiring connections, fuses, etc, and the problem is deeper... e.g., something like a blown ECU! hoping that's not the case

more to come later this week

sure would be nice to actually drive this car! :)

Fathead 03-12-2010 01:09 PM

Car is done, it got a new ecu at the dealer and NOW it can be driven.

Dead ECU huh? I had a feeling that was the case. Bet that was pricey :(

Travis' car eats money :eekdance:

But at least it's running now so it can get ready to head back to the track.

RCZ 03-12-2010 07:13 PM

Really glad to hear you guys figured it out!

travisjb 03-12-2010 09:56 PM

me too!

The car is in great shape for the most part. Junior went above and beyond in many areas. In a week or so I will try to do a full photo shoot so you all can see the details in high res.

I will be running in a Porsche DE event tomorrow to see how everything is sorted. First time at this much lower weight (no still don't have an exact number, sorry!). First time with new pads. First time with full cage. First time with splitter and wing. Etc. So the goal is very modest for tomorrow ==> see what works and what doesn't. I'm not out to set any lap records!

I also won't have the video/data hooked up for tomorrow, unfortunately, but that should be in for the next event which is 1 week from now.

Finally, there is an electronics issue remaining with the car that we still need to figure out. Car registers "N" only for gear select, so the SRM is inop. I'm going to have to use my god-awful heel-toe skills! The three gauges on the top fail to light up. And it seems to me that the power steering is running at 1/3 power at best. But regardless, the car works, so I'm very happy to just have it running!

More tomorrow.

RCZ 03-12-2010 10:21 PM

man how did things go so wrong ?

travisjb 03-12-2010 10:48 PM

I can only speculate... and it doesn't matter really, key thing is to dig out and get the car sorted

That is good, hope you guys get the rest of the system working 100%, but glad to hear the car is running and you can hit the track.

Its a new car with new style stuff so we had to toy with things to get them to work. ECU damage was not my work or in my control.

travisjb 03-13-2010 09:20 PM

Turned a 1:04.75 today at Firebird West. I may have done better than that - not sure - I only had someone timing me for a couple laps during 1 one of 5 sessions, so pretty sure he didn't get my best. In any event, course records are below. I am a few seconds off the pace for the course record for my "TTS" class. My car is still 300 pounds over weight (or underpowered) relative to my class limit, so I'm running a lot more like a "TTA" car right now. I also think I can pick up a few tenths with SRM - for some reasons my brass balls factor goes up when I use it. I'm overall happy with the result. Today was just a Porsche Club DE, will do this "for real" next weekend when the people you see listed below will all be lined up to compete! :)

Will post more thoughts later tonight on remaining mechanical issues to be sorted. Sorry, no vid today.

travisjb 03-13-2010 11:02 PM

Big stuff
  • Fuel starvation... still need to fix this... haven't made any progress and it is going to be needed to drop a couple tenths off my times
  • Brake issue... I had the "ICE EFFECT" big time today and it was embarrassing... the chief driving instructor thought I was just being an idiot when I slowly grinded to a halt half way through a carousel... I have a new theory about what is going on that I will explain on the thread Chrisslicks started http://www.the370z.com/brakes-suspen...tml#post444488... I'm going to proceed with more brake cooling, but that's *NOT* the root cause, I'm fairly certain
  • ECU issue... I want my SRM back! could be as simple as reprogramming the computer... it is new and the dealer didn't have time to program it... could also be we have another short, blown circuit or disconnect somewhere... the three center gauges are not working... I haven't even checked the fuses yet, so that's the first order of business
  • Rear diff cooler setup

Smaller stuff / lower priority
  • Connect transponder, reconnect traqmate/chasecam
  • Splitter ver 2... need to revisit the fasteners - they are being sheared off whenever I scrap the track - will post more on this below
  • Fluids... gear oil, motor oil
  • Setup... I'm thinking about -3.0/-2.5deg camber, neutral toe front, -1/8 toe rear, and 5.0deg caster front...
  • Stiffer springs... I'm using 10/12k springs now and I'd like it to be stiffer yet... won't happen in 2010, but eventually something like these Moton 3 Way Adjustable Nissan Motorsport Dampers with 800+lb/in springs

travisjb 03-13-2010 11:23 PM

Junior, as for the front splitter... it was held up well overall and of course got lots of positive comments from folks at the track... but there are a few issues we need to address

- screw heads stick out on the bottom of the alum plate, and so they are getting shaved off on the asphalt
- as a result, there is a danger the splitter will work loose...
- and it becomes impossible to remove the screws with hand tools because they are half way shaved
- 3 screws completely wasted today... and 1 of the 2 front turnbuckles was disconnected for same reason
- I had to put the car on my lift between sessions and grind off what was left of the screw heads so I could drop the splitter
- It was very easy to remove the splitter once I did that, so props to you for the quick release setup! that part was perfect!

Here's what I would propose:

- the 1/8 alum needs to be an absolutely flat surface with no fasteners sticking out beneath it
- I think we need to mount the alum to the boatboard with bonding material only - no fasteners
- then we cut holes in the alum so we can recess the fasteners that will attach splitter to frame... result = 100% flat surface


I ordered fasteners below that we can try:
  • #9679 - Machine screws, Phillips pan head, Stainless steel 18-8, 5/16-18 x 3/4
  • #14350 - Sex bolts - Phillips truss head serrated, Stainless steel 18-8, 3/8 barrel (5/16-18 thread) x 3/4
  • #14873 - Standard elevator bolts, Stainless steel 18-8, 5/16-18 x 1
  • #2564 - Hex nuts, Stainless steel 18-8, 5/16-18

damn dude you are intense. This is sweet, We will have to meet and run firebird when I visit my family

ChrisSlicks 03-14-2010 08:08 AM

Both the transmission and the gauges use the CAN bus for communication. You might have to go back on a Consult-III to troubleshoot that one.

I haven't had a chance to push my AP brakes to the limit yet, weather still sucks.

The whole system is CAN, thanks for the diag I got it covered.

Just curious...were you and Junior able to install the diffuser that I mentioned long time ago?

Maybe you should just install a racing fuel cell at this point. I am certain that you have already considered this.

ads370z 03-14-2010 10:35 PM

You need to drill countersunk holes into the splitter, and use tinnerman washers.

I will be out Firebird West this Saturday as well, driving my S2000.

thanks but not just yet, Mr Zless... the 104 target applies to Phoenix Intl Raceway... add 4-6 seconds for typical spread between the two... For a track record, I likely still have 4-6 seconds to make up at PIR and 2-3 seconds at Firebird.... very long journey ahead! :)

These, huh G-8 TINNERMAN WASHERS from Aircraft Spruce Sounds good. Amazing how many racing parts come from aviation

Look forward to catching up more next week

It's one thing to be on the ground.. it's a whole different animal to be in the air.. LOLOL.. :tup:

ads370z 03-15-2010 11:02 AM

I have worked on many World Challenge GT/Touring, and some ALMS machines. The tinnerman washers were used by most of the top teams, and really are effective and the best solution that I have seen to mount a splitter. This way you keep a flat bottom, no chances of tearing off mounts, and you get the benefit of a washer helping to distribute the load evenly on the mounts.

Let me know if you have any questions. I have worked on a couple splitter designs for GT3 Cup cars, and I have a full solid model of one for my S2000, done in PRO-E. Just dont have the time/money/tools needed to build it :(.

travisjb 03-16-2010 11:15 PM

thanks ADS, washers ordered from aircraft spruce!

so... back to a topic that I said was closed... can't help myself... what do you guys think about this one? lol

http://five-star-ford.ebizautos.com/...px?iid=4905195

What's a fair price to offer?

travisjb 03-17-2010 04:22 PM

Can't remember who I sold my center console to, but I need it back. Or need another one... it doesn't really matter what condition, just need one to comply with RTA Modified rules... anyone have one or know of someone who would? Thanks

http://i656.photobucket.com/albums/u...b/IMG_4158.jpg

theDreamer 03-17-2010 04:23 PM

Does Sharif still have his?

Edit: He might be using his to comply with rules also.

travisjb 03-17-2010 04:32 PM

thanks. yes, he'll need his for RTA modified... I need to find someone that is going unlimited class

FWIW, I haven't heard of any 370Z builds for time attack unlimited class. Maybe try junkyards to see if anyone has a 370Z yet. If they do, chances are the center console is in good shape.

LateralG'z 03-17-2010 06:46 PM

Good truck choice

Fathead 03-18-2010 09:55 AM

Can we just stick a 350z one in there and make it work?

travisjb 03-18-2010 10:45 AM

I asked the organizer and they said 'no'... lots of sensitivity among the tuners about cars looking at least somewhat stock.... I need to put the stock rear glass back on too... I'm going to miss the march RTA anyways, so no rush... just need to get it done for the April 23-25 RTA event in Vegas
