lol I just set it the injector voltage to those settings is that why it just idled like **** So what should I set it as? I had the scaling at 670 and just changed it to 636 along with the other ones you posted

double check what I posted if it idles like crap as that is the scaling I use for 90% of the Denso 720 equipped evos that come through the shop.

Here is a better way to read it:

Yea here's mine, it just seems to not idle too great and dips down. I slapped in the injectors last night and just been doing some logging today. I used the ams injector latency master and only changed timing alittle to get rid of a few knock counts. But this idle is killing me



Thank you for all of your help

If your idle is crap from just changing to Denso 720cc and using those settings then something else is amiss. Have you logged your fuel trims?

so after logging fuel trims they are as follows

Fuel Trim Low 100%
Fuel Trim Mid 130.469%
Fuel Trim High 98.438%

and these stay solid at those numbers

I have the latest version of ecuflash and under my injector size scaling it shows no size, instead of 513(stock) it shows a [.], thats its and cant seem to make any adjustments. I am set to developer mode, any suggestions, just got new injectors(780cc) and am about to begin with latency and scalings.

Either switch to a ...15 rom or search on this forum for the proper defs to add to your ...13 rom.

Ive got some PTE 680's. I've scaled it at 597 and used the AEM latency table numbers. It runs fine once warmed up, cruise afr in the 13.5-14.7, but when the motor is cold, it is really lean upon initial throttle. It runs in the area of 18-19 afr when i give it gas when the engine is cold. I was wondering if anyone else has seen this problem and what you guys did to solve that. I've tried to increase the accleration enrichment to max (1.99) and it doesn't do anything..

Sounds like too lean when in open loop. I would tweak your scaling. Do you have to abnormally richen up the WOT part of your fuel map?

Yes it is in open loop on cold start. He shouldn't have to touch his fuel map if he gets the scaling correct.

btw I think I've got it all sorted out I just had to play with scaling ended up at 622 and just had to keep playing over and over etc.. it is pretty much a pain in the *** I didn't touch my fuel maps at all
