Torque shaping?

[MikeOD]

I didn't bother to disable DoD since I've never seen the car go into it anyways...but I guess it won't hurt to flip the switch. PE delay is disabled, and enrichment ramp is at 1.0...it enriches target AFR imediately when I hit the pedal. I just added to the driver demand table to keep the throttle all the way open at full throttle...it won't stay at 100% if I don't have it cranked up that much at 100%.

There is a relation between peak tq values and DD. I've noticed if peak tq is too low you need higher values in the DD and vice versa

Oh ok...so once I get it on the dyno and know what the actual TQ numbers are, then I need to correct the peak TQ values and I'll be able to make the DD table be more realistic?

I mean...it's a manual transmission and the throttle response is awesome now...the rev matching feature works perfectly...so I can't see it being super necessary to get it all 100% correct other than to learn more about how it all works and make things more correct...which I do want to do. With an auto I'd think it's more important to be correct to control line pressure and shift time.

Do you guys leave the knock enrichment fuel stuff alone or do you disable that?

[MikeOD]

How do you guys calibrate the TQ coefficients? Is there a VVE like program for that or are you using Excel?

[Ben Charles]

For me it's trial and error on the tq coefficient tables. I've tried only adjusting certain rpms of the table and it has effected the entire rpm curve. For the most part you need to increase the values to make "more tq" or vice versa to lower it.

On the negative values its the opposite however

[MikeOD]

I'll try to figure out the equation behind it and build a model in excel or something.

I've been logging with 2.24...I'm used to it, and haven't really had the time to play with setting up the 2.25 scanner the way I want to yet.

When I run pure MAF and smooth the table it throws the AFR off...it wants the table the way it is for the AFR to be within 1-2% of commanded.

I intend to dial in VVE on the dyno very soon, I really can't do it on the street in this car, I'll wind up in jail.



Torque gain tables? Where are those?

Do you mean the spark advance torque gain?

Yes, I've found anything killing spark usually makes tuning correctly a pain, plus if it's killing or limiting spark, it's usually limiting torque In some fashion as well... I've had them act like slugs in 2nd gear only to realize I forgot to zero these out
