Thanks Matt!

I'll adjust just by the numbers, ignoring the labels.

I noticed looking through my R32 RB20DET maps, that all of them seem to have the Soft and Hard cut labels reversed? Maybe i am not understanding something here. All ROMs show a HARD cut of 7550, and a SOFT cut of 7800. Those labels should be reversed should they not? Soft cut pulls timing to slow rp...

Did it help you?

What are the disadvantages to setting the ttpmin to 1 accross the board?

I'm running 94 octane, chevron fuel, and still found it necessary to ignore the "Adjust crank tables" feature of injector resize. I figure i will be richening most of the map over stock, at least the colder values.

Thanks for your writeup rom. From what ive gathered, the rest of the enrichment tables shouldnt need much modifying if k constant has stayed roughly the same ( as in my case). The crank enrichment table is a injection time based table, and will however need tweaking. now in latest beta matt changed ...

I'm not sure if you have covered this torque, but have your TTPMin values been adjusted. I'm fairly new to all this but from my understanding they are the minimum pulsewidth values the ecu will allow even if there is a lower TP value. It may be overly rich on startup/idle from too high of a TTPMin v...

Sorry it changes over at what looks to be 65 degrees. There is a value called "Warmup timing TEMP max" which defaults to 65 degrees. Changing this to 0 would effectively eliminate the warmup timing table from being used as far as i can tell.

Idle timing is based off "Idle/Decel RPM Timing". However at low rpm and throttle position, the warmup timing map is used till ~55 degrees. >3000 rpm also uses reg timing map, and after a certain throttle position it jumps to regular maps. I found that i would have a very noticeable bog, w...

Just the crank enrich

I just changed the values back to original. Car starts much smoother. Increased colder values 0-20 richer than stock. Seemed better. Will have to play more.

Should be ms for cranking table since its just a raw value read and used for injection time. I need to check it out further to see why RB FT_INJECT tables are ms and SR20 ones were % I think they all should be ms but need to double check why the SR20 definitions from the XDF files were % Mine is rb...

Torque wrote:Thanks Matt .. Crank Enrich makes more sense I suppose.

But is the scaling actually time or %???

Any answer for this?

I fixed this problem on a local car the other day. It was an Rb25 neo but he was using an RB20DET ECU. It's the warmup timing table. Stock values are 7 degrees - which kills power and makes driving while warming up a real pain. I changed it to 20 degrees and owner reports problem gone. PL Exactly. ...

does it sort of bog down until a certain rpm or throttle position? I was having that too. I adjusted the warmup timing table from 7 degrees to 12 degrees.

Helped with driveability. Much more enjoyable.
However it takes slightly longer to warm up due to cooler EGT.

I'm using an R32 RB20DET ecu/Type 2
I always understood the crank tables to be in time as well. But now i'm not so sure anymore. Hopefully someone can chime in. Here's my modified vs stock table
