tune. no sleeves
tune. no springs
tune. sucks to be you, all those good parts and hard work.
if there is a mechanical issue, then perhaps you could call it a contributing factor.

I have driven 2000 miles with a massive air leak from a phenolic spacer, car ran like crap, would not run right, dynod it even so to figure it out, drove it home/
pistons were fine. fixed leak motor good.

so I have to say,
tune
runaway detonation happens fast.

I have egt, it is useful inded, but egt wont help you, the egt doesnt climb fast enough to tip you off, runaway detonation kills the pistons before you get a chance to even read the egt gauge.

Well, the timing maps sure got smacked...no question there. I question the approach...I am not claiming to be any expert, but I have been tuning a while. If this car still has a returnless fuel system on it, then it would seem the IFR table and the associated voltage comp table isn't right. The PE table seems bass-ackwards too. 1.26 sloping down to 1.16 EQ ratio?? I tend to be richer than other guys tuning, but thats quite lean. The way I look at it, your whole tune precipitates from the correct injector data...if it begins with incorrect constants, then all other variables that are modified assuming the injector data to be correct get skewed. It kinda looks like this is the case to me. The PE gets "raped" to get fueling where you want delivered AFR....but the timing fails to deliver...maybe the g/cyl wasn't being logged and he struggled to find the row the table was drawing from? This explains the "blanket" applied to a large general area. Not sure if anyone agrees with me, maybe someone else will chime in. Thoughts/opinions?

After hearing that, I'd have driven away.


Another crap tune strikes again. Sucks to hear, but hopefully you can build it better and get ahold of someone who knows what they are doing when tuning LSJs

Ouch. I don't think my engine would like to hit that timing wall...

I would be willing to bet that the tuner was removing fuel via the PE table instead of properly calibrating the MAF. Just because the PE Table was commanding 12.6afr doesn't mean the car was reaching it. But if it was...

And did you notice how the last few cells in the Maf were left alone? That might be fine to leave those cells alone if the car will NEVER hit those cells but if the owner were ever to pulley down or go from an hot indoor dyno cell to some nice cold winter air that could increase air flow. Even if I don't hit those cells during logging I still scale them to make sure the tune safe.

It's hard to pin point the issue on one thing since there are a lot of incorrect things with that tune. Maybe if we had a log file we could see more.

It appears the tuner went out of his way to destroy the base tune you provided him.
