:worship: SOLVED!!!

The Idle Spark table and Coast Spark Table were all jacked up. I pulled a tune for a stock 2010 ZR1 from the repository and copied those values over. Flashed the tune and...

Forgot to put in my mod list I have ID850's. So putting those tables back to stock is not an option.

Ok, I am lost. If I am driving the car and want to coast to a red light or do a pull and push the clutch in to coast down on speed the RPM's will slowly drop and the motor shuts off. This only...

Solved:

Its the little things that bite ya.

So a buddy looked at the tune and said I def have a vacuum leak. The P0102 is a good sign of a vacuum leak somewhere.

Started going back in my...

The car will do the same thing if I force it to stay in OL.

One thing I have noticed is that will usually start acting up when I leave off the gas and decal. The PCM will stay in Fuel Trim...

Hmmm... I just don't understand why the STFT will hold then even though the WB comes back to 14.6-14.7 which is what the PCM is commanding.

Update:

Negative... My Sky uses the exact same MAF. So I switched them. Car did the same thing.

Ran fine for 15mins then when rolling to a stop light, the 02s steadied out STFT tried pulling...

Update:

Took the car out again, cleaned the connectors on the 02 sensors. Looked great for the first 15mins then it started doing the same thing, trying to pull fuel, 02's get in a steady state...

Ok, I've been trying to track this problem down. On the way home from LSFest my car all of a sudden developed a buck at steady cruising speed. Not a constant buck, but all of a sudden, felt like...

Ok guys, I'm a HUGE lurker in HPtuners forum. Generally because I can find my own answers just using the search. So I've got my 2010 ZR1 all tuned in line. A somewhat conservative tune, feel it...

ok. checked the wiring harness, everything looked good BUT i had someone tell me how to test the voltage.

Had an old 02 so i cut off the pig tail and plugged it in. Started the scanner and...

i removed the sensors and zip tied the plug ends up outta the way.

I am goin to check the wires and try cleaning the contacts.

yea, I don't understand why they stick to those values.

Brand new sensors, everything looked fine when I plugged them in.

I just took notice that B2 is not toggling. It is hanging on 450-455mv.

B1 is toggling around pretty good. I am goin to check the wires tommorow night. Still think there is more to it. :(

Ok, so I drove the car around last summer OLSD tune. Would hold 14.7 great but would require tweaking every so often.

Decided to get to turn the 02 sensors back on. So put in brand new Bosch...

is that a true GM MAP sensor? I picked a MAP sensor up from advanced auto and it was wrong.

sounds exaclty like the problem i had. wrong map, i could fire the car up but it wouldn't idle, would...

tuning is the same as before. just now your not goin to turn the MAF back on.

I found it much easier to tune w/ the 2bar setup then I did w/ the MAF. My biggest problem was finding a wideband...

not being predictive when pulling timing.

had traction control turned off both times.

One thing i did take notice is in the -3 log my timing drops down to 8* and then comes back up to 13* and...

Ok, over the winter I built a forged 347. Speed Inc SC3 blower cam, 10-11# of boost. Fuel pressure holds steady @ 58psi and injectors only go up to 85% duty cycle.

Diamond blower pistons -8.6cc ...

Thank you. I skipped right over that.

It just wasn't making sense on why i couldn't see the PID. I'll give that a shot and see how it works out.

Ok, I have alittle problem.

Helping a buddy tune his turbo TA. Put a 2bar SD tune in the car and the problem is when I go into the VCM scanner and try to change the MAP from the standard SAE...

The thing is this has been an on goin problem.

Ever since I put the blower on the car I have been getting false knock, the tuner I took it too the first time (this is 5 years ago before I had...

opps, that i had my sig updated for this forum.

check it out vvvv

So today I ended up throwing my car on the dyno.

First pull was low, but I figured I would have some tweaking to do anyway.

It was 11.1-11.4 on the AFR so I cleaned that up and got it to 11.7....
