What are the issues?

Andy

i havent read through every page, so forgive me if this has been discussed, but my launch control does not build boost, sits at -10vacuum

Try playing with your timing in that area.

Andy

ok i will log and see whats the load at, i have it set for 5k for testing purposes, i noticed the group N pops alot more and quicker than the tinywrex launch control. also should on the regular group n launch control that is on the map already i have fuel cut at 5k, should i change that??? could that be the issue that its doing launch control and fuel cut, therefore not building boost, but rather acting as a revlimit??

That's really all launch control is. If it were my car I would have my rev limit set to 7K and my LC set to 5500. You should be able to adjust all of that in the standard RR defs.

Andy

ok man thanks, before i had it at 5200 and it was great with my vf37 set up, i will mess with that and see what i get and should i retard timing

Andy or anyone, maybe you could help expedite this for me, I was trying to get to the routine I was trying to figure out which function sets the CEL light on in this ROM, I am currently on function sub_12FE0 though I am not a 100% clear on it.
Reason is that I have found out that on the JDM spec cars, the CEL DOES go off (and stay off unless an OBDII code is generated) if after start one lets the engine to warm up to operating temperature before driving. I think the ecu is checking for more than just ECT before switching off the CEL, hence my heightened interest in the CEL routines.
Has anyone experienced similar results on the USDM spec vehicles?

I thought there was talk a while back about the initial CEL during warmup on JDM ecus being AVCS related.

As far as 0x12FE0, it is related to the CEL logic, you are correct.

ok i read through about half the pages on this post and i think i got lost on page one.... or too excited after seeing the ignition dwell picture. what ecus are you guys using? did you just use this defintion for any ecu to adjust the paramaters? right now im running a ver 8 ej207 using a ver 7 ecu and 16g turbo, i have taken alot of tuning parameters from different ecu roms and adjusted accordingly to match my current setup. off the top of my head i can not remember what rom id im using right now but but i was always wondering why i have multiple timing maps and multiple fuel maps, i never knew which one was being used at any given time. so i modified to be similar. any info would be greatly appreciated.

Love the concept and the work that is going into figuring this all out for the 16bit boys! I anxiously am waiting for the cells/FBKC/FLKC stuff to get worked out, going this in depth into the ecu is definitely beyond my ability!

Andy, I have a question about the cell routine. What does the cell routine do when the ignition is turned on vs when the engine is running? When the ignition is in the on position I know the cel will be lit, and when the ignition is turned to the crank position and the engine fires it runs a check and then turns off the cell. Could the cell be related to an ignition difference from the jdm?
Just throwing that out there. I have been through all the wires in the dash for the cell and didnt know exactly how that part of the cel routine was done.
Really the more I think about it that doesnt really make sense, and the ignition shouldnt really matter should it.

i can care less about the CEL all i care about is Antilag and Speed Density. once antilag is switchable im defenitly using this map. or at least when its more predictable to enable.

You can still turn anti lag on and off by flashing or set the perams for anti lag so it doesnt become active under a set rpm. Why do you want the anti lag? It doesnt work like a true anti lag unless you have the correct hardware like a real group N car. Its close though...

building my own stage rally car for around my farm. 03 WRX with a full cage, gravel tires/suspension/wheels etc.

and i love the sound. im at least cracking my throttle plate open and setting timing low so it idles like a GPN car. antilag would make it even better

elevenpoint7five, just wondering if you could send me the fixes you have, i'm about to smash my maf for good. I think its bad, i'm getting super rich AFRs at WOT and my tune hasn't changed. I wanna switch to SD for good. I will PM you my email.
