Can anyone help me find the acceleration enrichement for my rom.

I'm using 88840017.

Thanks a lot.

 

The acceleration enrichment table listed in ECUFlash is not really acceleration enrichment, so no point to try to find it for your ROM.

 

Thanks a lot mrfred.

I have RC 1000cc's in my car. Perfectly scaled. cruise trims are always between -1 and 0%, idle trims are usually dead on at 0%.

I had some start up problems, but I found a thread with the IPW table for my car, and it got fixed.

I feel i still have some throttle tip-in enrichment problems, as when the car is on overrun, a slight tip in the accelerator pedal will sometimes cause some pops in the exhaust.

I never noticed it before the injectors though. It's nothing unbearable, i just feel something is wrong, and it could be fixed.

Are there any other tables I can tweak around with to tune the injectors even better?

Cars run perfectly, as good as stock other than this issue.

 

It might sound like its dodging the real issue, but if you haven't increased your timing in the low load cells, I suggest trying that. Not only will it improve low load performance, but it will probably also get rid of the tip in popping.

 

low load as in around 10%?

IIRC, those are the load cells i am at when i am on overrun...

 

Yep. What values do you have in those cells now?

 

we're talking 3000rpm to 8300rpm, 0-70load right?

if so, a big block of mid to high 30's

i'd say just like they were when stock, my table is rescaled on both axis, but i think those values correspond pretty much to the stock table.

 

Its rescaled? There are several other tables besides the ignition timing tables that rely on those axes values. You might be turning on the EGR system at the wrong time or some such thing. Might be good to first start by returning to the stock axes.

 

really?? from what i've been seing, it's common practice to rescale them.

i have them rescaled for more precision in my higher load/rpm columns. :/

what other systems/table use the load/rpm axis of the timing table, because no other table has changed in ecuflash for me.

thx.

 

There's lots of tables not directly related to power tuning that use those axes. They're not shown in ECUFlash because they provide no tuning benefit. One example would be the recently found low temp timing trim tables. Messing with the timing load axis can cause low temp timing trim to be used in load cells where it was never intended.

 

thanks a lot mrfred, i'll fix them up when i have time.

i think you should create a sticky about it or something, as it's a common practice to rescale the low loads table for better resolution at high load/rpm points, and very few people actually know they might be ruining other tables.

 

Hi, what did u scale the injectors to and what latencies for your RC1000cc?
