There have been some topics about ignition timing in crome, especially high cam and high rpm values being somewhat advanced compared to the tables/other systems. I have noticed it a lot more when using crome, not sure exactly why. So the best idea is to start with a conservative timing table and go from there. There is absolutely no reason to get aggressive with the ignition timing with out being on the dyno.

I honestly don't use crome very much because I have noticed this kind of thing for a rather long time actually, it is just now hitting the surface. Not saying that there is anything wrong with crome, just some of the ignition tables are in question right now. This kind of thing is also built into the stock rom, which wasn't made to be boosted, so that should be taken into concideration. That is all.

 

oh WOW...i had no clue! I heard crome was buggy, but damn! That crap could have potentially cost me my block! If this is the case and crome timing isn't pinpoint, then what are you using to measure timing? (please don't say Uber...i hate uber!)

I personally use neptune on my cars. But I tune mostly uberdata, but crome if it is needed (ITBs, 3bar or big injectors) since it has better support for such things.

Crome is still perfectly able to tune your car, just get it on the dyno to get the timing worked out with it. Uberdata and even stock code have this timing correction in higer RPMs, but for some reason, it seems that there is just something amiss somewhere. I don't want to spread false information, so don't take it as perfect fact, just wanted to fill you in on personal preference and new findings.

 

yeah..i just did some research. Crome's gearing/timing for certain ECUs are not completely accurate at higher gears. but there are ways to fix the problems though.

Na, not talking about the per gear trims. Because for a long time, when crome was supposed to edit fuel per gear, it was actually editing timing. Two different things we are talking about here.

 

2 factors are most important to running low times in a turbo application:

1. Area under TQ curve.
2. Traction.


More is better.


oh yea... and ...
( and type R stickers =P )

 

precisely my friend. This is why I believe maxing out a smaller turbo is much better than using 50-60% duty of a larger one.

 

so what do you guys think about running high PSI on stock blocks?
