P59 w custom os 3bar

Under full boost car will go into reduced engine mode with zero throttle response and tune has to be reuploaded to clear it. Any ideas on what to check ?

Fixed wot adjusts perfectly to 11.75 but no matter what changes I make to the tune it idles at 9.8 to 11.0 . 20 deg idle timing to 27, pulled fuel etc. P59 ecm. Commanding 14.681 smokes almost like...

bosch 210s, zr1 3 bar map. makes 15-16 psi. Should I disable the maf if I go back to that OS ? and the fact that the table only goes up to 105 isnt a issue?

On speed density enhanced OS it drove perfectly when in boost. I read the tune file and saw that it was not 3bar and the ve table stopped at 105. Out of boost it drives perfectly. Only change to the...

I have a turbo 4.8 looking for an injector that will work for me on 93 and e85. It needs to flow 700+
Ls2 height id850s or bosch 210s? Or do you have something else you recommend? Don't want...

I have data populated in cells, for example 100-150 kpa. Nowhere in the playback of the datalog can I find that event. Am i doing something wrong?

Anyone having the same issues it ended up being the map sensor

Thank you john. Ive been dealing with this for a couple months now. Map sensor went bad and did not throw a code. Swapped out the ZR1 map sensor for a 2bar cobalt ss one and it fixed all the issues I...

Key on engine off was 0 maf 99 map
engine on idled at 58-60 map

now it idles at 86-90 kpa seems very high what could cause this?
Key on engine off went from normal to 0 maf 50 kpa map

That sounds accurate I will try messing with this again had to take a break lol

My tuner got this data not sure what he uses. I've tried other settings that I have found. By the way they are deka 60 long style. I noticed the tunes he sent were all for the short 60s. I've tried...

I went data logging the LTFT and had -18 -14 in most cells , I multiplied by percent - half on the ve table and the hesitation got worse. Also after datalogging that tune still had -14 in most cells....

Two logs

That probably has something to do with this. I don't believe that is correct

Yes correct tune is flashed, ran perfect this way for months. Drove like stock. It's a ccp jam cam

They are deka 60 they flow 72 at Ls pressure, yeah drove perfectly before. This tune is from a reputable ls tuner. Not sure what changed .

Just attached both

- have had this issue for almost 2 months now.
First when car is started and idling I get a very heavy fuel vapor smell. I have part throttle sputtering...

I updated the eq ratio to 1.25 all the way across, tuned idle and airflow for cam. I have the injector data now but not sure what do with it? New to tuning. These flow at 72lbs at ls fuel pressure

Swapping them out anyway for the 60s

This was the tune installed on the vehicle when I purchased it. He was running the 24lb injectors, I am going with deka 60s. Car is also boosted so that needs addressing. Supposedly this was a dyno...

2004 Z06

Was switching to new injectors and saw that they were only 24lb injectors, these were the settings for flow rate 82.7...
