    What's the total amount of timing the V4 can retard timing?? 6 degrees, 8??

    Wondering with cps offsetting, how much total timing can the V4 retard?

    Good Q.
    Let's hope for an answer.

    I remember Shiv once wrote the Procede can retard the timing by up to 6 degrees. But, it is better he clarifies this himself Click here to enlarge

    Edit, I looked around and found posts where both Shiv and Adrian claims the Procede can offset timing by up to +/- 16 degrees http://www.bimmerboost.com/showthrea...2396#post12396 This means a lot regarding safety in N2O applications.

    wow, that much.....though their current maps pull a maximum of 3.5 deg I think? assuming 100% Ign correction.

    I was going to start looking for that, good job, thanks for posting it.

    Why only 3.5?

    3.5 degrees is a lot for the N54 engine and corresponds to about 10 degrees for an conventional (non-DI) engine. If the full timing capability of 16 degrees for the Procede was used for a fixed 100% IC it would mean that the engine would be ignited close to or even after TDC in most situations. This would cause an incredible thermal load on the exhaust valves etc., and the power would be severely reduced.

    Ha, yeah that would almost be like an anti-lag setup!

    So correct me if I'm wrong..... I've seen Procede users say autotuning would adjust IC to 10-30% with pump gas so that would be 0.35 deg to 1 deg less advanced than the stock tune right? Some have even posted 0% IC on 93 pump. Wouldn't that be the same as what the JB3 does in the 0% IC case? I know Shiv mentioned that even though it logs IC- 0, they still say it adjusts, but it's so minimal (less than a sec) that it won't show up on logs. I am also aware that boost is a direct variable of IC, boost was shown to be autotuning to the normal 13-15 psi depending on octane/quality of fuel.

    Not a fanboi of either tune just trying to do some deductive reasoning....

    Keep in mind removing 1 degree from the CPS absolutely does not mean the spark is occurring 1 degree closer to TDC. It is not a 1:1 relationship unless certain conditions are met. Like the DME observed advance is sitting at its ceiling curve of ~11-15 degrees 4500-redline. The average "autotuned" car is running 30% IC which works out to about 1 degree of offset. And that 1 degree of offset works out to somewhere between 0 to 1 degree of timing retard based on many conditions. Basically nothing.

    That already took place in the Haltech thread, you are in the clear.
