Ok so i finally got steven on the phone and we've determined that he has OEM modified wrx injectors. That means they flow 740cc of fuel :P. This is why any time he touched the throttle it went crazy rich.

So I'm going to attempt scaling his injectors at 650cc rating to compensate for the different fuel pressure. I'm upping his latencies to add fuel back to the idle pulse which i'm modifing with this setting.

I'll also send him another file with injector scaling as the only thing touched and leave the latencies alone in case i'm way off and should get him moving

 

i dont get any call from you im so jealous lol

 

Some pictures for future modders

Decapped vs Capped:

 

I thought we did talk

Maybe it was someone else then

If you want to talk just email me and i'll send ya my number

 

lol yea im pretty sure it wasnt me and cool i might just do that
oh and i think the maf compensation was the reason why i would lean out at wot, i did a lil test and bumped it up in the upper region and gave it a test and noticed my afrs were lower then before

 

cool

 

yeah lol, omg after all this time, I have the ones on the left lol. Ok lets get this car tuned, and I will get you paid for your time.

 

Lol guys the scaling ended up being 731 cc on the ecuflash program. Latencies are 3x higher than normal wrx injectors. I think we have a winning combo though just need to clear up some startup quirks and she'll be good to go.

 

hey does anyone know if the evo 8 stock injectors are a direct swap in the 4G94 motor? If they are I might just buy some off roadspike so I can make his job easier with tuning

 

You get the latest rom tested?

 

yeah I got the logs, good and bad news,

Good - I can boost up to 3 and 1/2 to 4 without any engine knocks from the CEL, it looks pretty close on the boost gauge

Bad - when I get up to boost levels I can feel the car hesitate and now it seems like my afrs go up to 13 now when im in boost? they were good yesterday.

Also my idle went to to lean again, so I have to press it to get it to stoich, and when I do that it richens to 12.0 something and slowly goes back up to stoich and stays there. I will post up the logs for hornstar and I will email them to you.

 

Not really too bad of a result to be honest seems like we are getting pretty close

I'll guess the final scaling is going to be around 780 or so by the look of things. Seems we finally see the limit of those injectors and can begin zero'ing in on the final product.

 

sweet man im getting pretty excited, it would be nice if I was rich then I could just fly you down here and make it easier lol

 

you got email bro

here are extra logs

 

Kinda off topic I know but basically to go from 440cc to 880cc is a matter of pulling off the cap?
