hey guys i just got all new stock sensors (boost senors) and i was running 28psi and after i got the sensor in i cant go past 12.3psi and i tried tuning it my self(hp tuners) and nothing affects the boost and i checked all the routing and looks fine and vaccums line... im facking puzzled

 

Check boost leaks. Flash back to stock and rebuild tune. I had a similar issue when I installed my intake, couldn't control boost and it was spiking higher than the stock maps could read. Flashed back to stock and problem was solved.

 

Why did you replace your MAP sensors?

 

Did u correctly load the correct data for Ure sensors or get the correct sensors.

 

ya me buddy works at a dealerships and i thought my sensors were fucked and he gave me new ones.... im gonna try flashing back to stock ... cuz my fuel is like choking at idle bouncing everywhere and stall outs and dies ******* retarded... just out of the blue it started doing this after i tuned the the car with the new turbo

 

This is why I asked why you replaced the senosrs. It seemed pretty obvious that you were leaving something out. Now it appears that you swapped the turbo and made adjustments to the ECM before it started acting up. If you want help diagnosing the issue, you need to include all important information. If you tell us what turbo you installed, it would be a start. You would also need to include all other mods. Did you do the tuning yourself? What all did you change? etc...

 

55/57 precision dejon cai, hks catch can, dejon piping, external hks bov, hahn intercooler, honed intake, exhaust manifold valves, 3"dp "3 all straight piped from there, vince tunned then went to hptuner and now working with nick from byt remote tuning

the thing is i was tuned at 450whp and drove it for a month and then one day going to the track and i got to a stop sign and my car died, turn it on, my afr was ******* searching like a hobo looking for booze, was idling like **** and my advance was all over the place, i done compression test boost test smoke test changed pretty much everything minus pistons and rod and a new motor lol (i mean replaced with new factory stufff to clear that up ei the senors what not) and the boost solenoid was the last one to be replacd and yea 12.3psi is my current boost and idle is crap **

 

Well since nick is tuning you he should find Ure issue quickly.

 

ya hard to get in contact with him lol been 13 days since i sent my logs and tune back to him

 

Hey bro check ure mail ;P

 

Factory boost control or a manual boost controller?
Did you test at 450whp on the dyno or just going off the mods and boost level?

 

You must be bored today, Matt.

 

factory boost but i have a manuel boost controller coming... doesnt matter now.. pcm is friend i tried flashing back to stock and car wont start asks for vin i type it in now fml

 

I don't know why you are making this more difficult for yourself.

1. Why did you buy these complicated products when all you had to do was drive to zzp, a few hours away.

2. SSKev and Sean are good at what they do, why don't you stick with them, they are local, and if you pay them for their services they will help you sort out your items.

 

yea well i did go to kev... and i paid him several times and here i am now.. so

 

How far are you from our shop? If you can get your car here, we can get it running right.

 

I know you went to Kev bro, him and I discussed your tune many times. Take up zzp on their offer.

 

...... :P pop.......

 

lol well id have to tow the car to ur shop, and it about 6hrs away

 

Yeah, that is a long haul. Well, I hope you get it figured out.

 

thx matt... gonna try a gm reflash and if that gets my car running i might just buy a full built motor and everything from u lol

 

how were u able to run the factory wg solenoid with the precision turbo?

 

You need to make a Pid to calculate Ure wgdc and ect.

 

reroute the factory lines to the wg and bov for the precision kit as they are connected to the factory boost solenoid and then adjust as you would as if it were still factory. (ie: fasctory wg-am wg and factory bpv-am bov) this way the computer just knows its controlling the bov and wg it still thinks they are the factory ones installed and thus allows you to still correct for them...make sense?

custom histograms:
loadxrpm- reading custom boost pid using the in manifold map sensor and
loadxrpm- reading wg% actuated so you can see what is being commanded and what boost it produces so you can 1) make corrections and 2) know how far each correction effects boost levels

of course will also have to play with many other tables as well but those are wg specific

 

lol thx for answering that for me
