I have a question for people who installed this kit, how did you get your car to your tuner? (I know some of you are doing remote tune) I am thinking of renting a uhual trailer but wasn't sure if I could drive it up the ramps onto the trailer after the install... the car should run good enough to go that short distance right...and not really hurt anything?

or I just get it towed to my tuner (about 60 miles away) which would probably be a lot more expensive than a 40 dollar uhaul rental

Having issues starting the car... I switched from 600cc to 1000cc injectors. Shouldn't the car at least start? Or do you think it's running too rich and causing it not to?

If you didn't tune for the new injectors, don't attempt to start it! Your tune needs to be rescaled for the injectors.

Really? My buddy installed a twin turbo kit for his Z and the tuner said it was ok to drive to the shop. Just to stay out of boost. It fired right up and he drove it over. No issues. I didn't think the super charger would have any issues. : /

Yes really, if the ecu has the capabilities to adjust the fueling of almost double the injector, then this ecu would be the first I've seen with that range. Injector scaling is pretty specific. I haven't heard of anyone getting away with scaling an injector 400cc's (x6 injectors) off. That's A LOT more fuel being delivered to the motor than the car thinks is getting delivered. Was your friend on the stock, untouched tune?

Yea he hadn't tuned it yet... He drove it up and then got tuned. I stopped messing with it and going to get it towed to the tuner. Thanks for the info bud... I honestly didn't think It wouldn't turn on. You saved me a big headache of removing the manifold again to check the injectors.

Are u planning to throw it on the dyno since ur getting turned?

If he is towing it to the tuner, I'm going to go out on a limb here and say that he will be on the dyno already. ;)

My A2A install (using the stock canned Stillen tune) starts fine and idles fine but the drivability sucks. The tune is waaaaaaaay to lean with this setup. I finally got back to working on the car and took it for a short drive yesterday after replacing a bad fuel pump. Because the last time the car was driven (low fuel pressure) the ECU had fattened up the AFR to the point that it would hardly idle when I fired it up. After driving it around for about ten minutes it finally settled down at idle. Wide band says 14.4 AFR which is good. Driving the car is another matter though. When accelerating under normal (no boost) driving the car accelerates ok but as soon as I reach a no load cruise speed the AFR goes to about 17.5 which is bad, very bad. The car runs rough and isn't happy.

My plan is to go ahead and order a EcuTek kit along with license and get the car so it will drive so that I can get it to the tuner I want to use or have the Zen Master Seb remote tune it for me. John Visconti sells the EcuTek kit and also does remote tuning but I haven't seen many reviews on his work. Anybody got an opinion on John Visconti?

My Supra buddy is willing to help and he tuned his 800hp Supra himself. OMG, what a beast! His car has 220,000 miles on it and is still running super strong!

Back to what the OP was asking, my experience says that unless you have a AFR wide band gauge and know what the AFR is, you should not drive the car to the tuner unless he is located at the end of your driveway. Burned valves and pistons can result from running a lean mixture and oil wash down and ring damage from too rich of a mixture. Slightly off is no big deal but way off can cause serious damage.

If you get that Ecutek then get the very inexpensive map sensor and map tune. Almost every other kit i sold has gone this route.

Okay, more info please. I have not seen this before, or maybe I did but forgot......

These other guys that have done this should chime in but you swap that map sensor on the back of your manifold to a (3bar?) map sensor then tune on MAP instead of MAF under WOT conditions.

Someone should throw up the link to the sensor please.

I was gonna assume the same....but wanted to make sure...Good to know we're gonna have more numbers..:happydance:

Interesting. What the heck, with all of the money and effort into this project I'll look into it. Thanks Top!

I went with Visconti on my first EcuTek tune and I thought it was a night and day difference from my Uprev tune. Seb's tune was much better though and his communication is on point. I actually reached out to Visconti first to redo the tune, but he never got back to me after a few emails. He is pretty notorious for this unless you are one of his GTR clients.

As for the external MAP sensor, you'll have to contact Specialty Z to order one. I believe Seb did a hybrid tune with mine, but I actually forgot to confirm that with him. It was supposed to utilize both MAP and MAFs for tuning, so you get the best of both worlds.

Here's a pic of the sensor I'm using with EcuTek...it's a 3 Bar Haltech MAP Sensor...this allows us to tune via Speed Density using MAP instead of MAF....however the post blower/blow thru design on Topz kit will help a lot more with the SD tuning

Here's a link to StillenZ84's link that has it installed....

I've decided and ordered the EcuTek kit from SpecialtyZ and will let Seb do the tuning for me. They even offer a 4 Bar sensor that fits the OEM location as an add on.

I figured that I'm in this far already, lets get this project DONE! I WANT BOOST!!!!!!

This week will be like Christmas, new custom wheels should be in along with the EcuTek kit. I want to smoke some RE-11s!

I have many many bad things to say about Visconti. STAY FAR AWAY FROM HIM. I will bash that dude any chance I get until I die. If you have to do the remote tuning route Sebz is the way to go hands down. There is no comparison between him and anyone else. He is the best at what he does and is a really good guy to go along with his amazing tuning.

Just got off the phone with Seb and he's shipping my stuff tomorrow. The engine should be done this week so we are getting closer to getting the car back together.

You will not be disappointed my friend.

It's sad doing knowing its for someone else but I'm still looking forward to seeing what it does. I love the C7 but the Z has been such a long process it going to be hard to see her go.

:iagree:

Anyone have a copy of the install instructions for the a2a kit? My shop is working a quote for my build and needs this to accurately price it.

FYI I'll be back with results from install of the following by next month:

topgunz a2a
vortech impellar upgrade
800cc injectors
MAF upgrade
AAM Competition R-Line Oil Cooling System
TIAL BOV

There are pics on this thread, which should give them a good idea of how the install is going to be. It's pretty straight forth compared to the W-A setup, because you don't have to deal with routing the tubing and installing the pump.

Just replied to your PM. I have PDF's of the install.

Also, 800's will be fine unless you ever plan to run E85 and instead of upgrading the MAF's just use Ecutek and the 4 bar MAP sensor.

No plans to go e85 but thanks for input and suggestion.

I think there is a guy on this forum who had their car at Z Car Garage in Cali looking for the A2A kit. If so you should hit me up. Not sure what Robs plans are with your car but I'd like to help you out.

My Ecutek tuning kit just arrived from SpecialtyZ. Time for Seb and I to get to work!

Good luck man! He has a few AtA kits under his belt now so should go pretty quickly!

Is ur tune finalized?

For those running the turbosmart dual port BPV: Here is the blue spring that I cut last. I only get fluttering when I manually shift (7AT).

That's me. Need to save funds for the A2A right now and also subscribe to see the results.

Not driving the car too much right now but this is on the to do list. Charge temps are typically 140F when warmed up before entering aftercooler.

Was it just there this week?

Shoot, I meant, I was looking at an A2A kit and Z Car garage worked on my car.

I was not there last week. I'll talk to Rob about who is doing it though. They might not be on the forums.

Yeah, maybe not. Dont bother hitting up Rob for it if he is not on here. I was thinking it was you.

Let me know when your ready to go A2A. You have all the parts in play for it minus some fuel. I'd be careful with that 9psi pulley and SI impeller combo with the water system. We have seen what the outcome can be.

Yeah, I know the potential ticking bomb on my setup. I don't push her hard when the AIT gets high. I have a sensor right before it enters the aftercooler.

I'll let you know when I'm ready to go A2A. PM the shipped cost to 94544, I see a number on the first post but not sure if that changed.
Thanks

The day everyone has been waiting for! Dyno!!!!! Good luck guys! I know I have been just dying to see! Lol

All done with my pulley setup. It runs great. And actually getting 8 psi out of her with noticeable slip. Smooth through out the rpm range.

Gnarly bro. I knew it would work. Congrats! So, what belt length?
