Custom ported and CNC throttle bodies, upper and lower manifolds by Synergy Composite

DR_ · 12-01-2014, 06:46 PM

After installing the ported TB I got a MIL P0507 Idle Air Control System RPM Higher Than Expected. It did idle higher than before so I performed the idle air volume learning per the manual and that seems to have done the trick.

Has your P0507 code come back. Mine is idling right around a 1000 RPM and I cannot get it to go away unless I clear it with my OBII. Will up rev take care of this? Any suggestions would be nice..

You have no codes but a higher than normal idle?

You can change the idle target within UpRev. But if the higher idle is due solely to the fact that something physical was changed in the TB then I don't know how much it'll help. I assume you tried the TB relearn?

Now that I think about it my tuner might have just turned that code off. My turbo tune idles about 950 cuz that's where the system is most happy with all the changes.

Maybe someone with UpRev tuning experience will jump in and provide more detail on turning that code off.

He shouldn't have to do all that, no ones done it yet. The relearn needs to be done and all vacuum hoses and gaskets checked.

So no go? Or just to much to type? Give us something. I have money to blow..

FPenvy · 12-02-2014, 07:48 AM

it's 12-2...............

where's these dyno sheets?

conquistador · 12-02-2014, 09:12 AM

in for dyno results from Syno and other risk-taking members!

Btw, Syno's 370 sounds BEAST.

synolimit · 12-02-2014, 09:34 AM

I'm hunting right now and left ASAP after the tune. I have almost zero signal here. I'll post a sheet soon. Car made 6hp and 5tq at peak with ALL the parts (anyone wonder why Z1 doesn't show a before and after?) and 11hp down low. The car made zero between 4500-6500. The consensus is we improved the intake but his cats were holding us back for the exhaust. The owner is buying motordyne test pipes and coming back next week. We will pop off the mani and TB's and do it again. But like I said from the get go, 10 or hp is what we expected at this level of NA and for sub $1000. Over all the owner picked up 20/20 from tune and parts. For a NA in SAE this isn't bad!!! Went from 299hp to 319hp and 240tq to 260tq.

so the best gains were from the low bandsu nder 4500 and mediocre gains above 6500?

any reason why the 4500-6500 range was flat? i'm a bit confused on your 20/20 gains part... was this strictly from the ported or was this inculding a tune?

As I said in my reply you quoted, we believe we got good air in hence the 11hp increase from 2-4500 but the cats maybe killing us getting that air back out. We are not sure. Like I said also we will test this next week when the owner comes back with motordyne helmholtz test pipes and we reinstall his oem stuff and we do it all again. Also his 20/20 was his 1st or 2nd run vs his last. That means parts plus tune.

What are "ALL the parts" that you're referring to? Do we have a baseline dyno? With the fore mentioned parts and then after the parts with nothing else changed? What are we testing here?

I'm referring to the title of this thread. I'd thought by now that'd be obvious. Apparently not. So we are talking about ported upper and lower manifolds and CNC throttle bodies.

Yes we do have a base line. Trying to get the wife to text it to me but again I'm on the side of a mountain hunting so its hard with no signal. The sheet I will post with no parts plus tune, then parts with retune will be just that. There is no dyno with just parts because the customers car started to knock. His final tune is actually less timing then it should be and what the stock parts plus tune had! This automatic car was giving us much headache.

i guess this isnt a before and after posted by Z1?

here's the thread too. just in case.

this Synolimit fail brought to you by: FP

This is FP at his greatest never knowing how to read! Way to post the 400hp pack in a thread not taking about the 400hp pack! Way to go champ!

Now use your useless skill had find a dyno that's relative to the thread. Show me Z1's before and after ABOUT THE THREAD TOPIC ONLY!! that's right, you won't find one like I said. Z1 only shows their ported mani vs a m370. Zero proof of a ported vs unported because like I've said!! I bet it's only good for 1-2hp! We believe we can get 10/10 across the board but only with all 3 parts!! Exactly what I've said and I expect from these items.
