i think you could increase the maf size and lower your latency a little. since at idle, injector pulse width is prob about 1-2 and at wot it can exceed 14, so decreasing latency wont have near as much effect as it would at wot. i might have to try that as well when i get a chance.
i also see max load between 90 and 98%. at this point my maf reading is around 950 hz. i am thinking it should be more than this but havn't been able to compare to other turbo lancers yet. can yall see what your flow is at wot?

 

ok so i just checked and my stock maf size is 215.7 g/s ???

 

Crap MAF scaling isn't defined in my ROM.
I'd try it right now!

We need ecuflash gurus here

 

ok i kinda got mine scaled but some of it looks diff from the evo guys.

and what is the actual maf size is it 29 or 215 g/s because i can change it between these based on my endian value.

 

Did you rescale your load values?
I never touched mine so that may be the problem.

 

Ya i thought that might be a possibility. So it.s a problem with the ecu not letting the injectors open properly...hmmm i got my load tables rescaled, maybe the ecu doesn.t reach the added load areas

 

Once my fuel trims settle I'll try to rescale my load to 120%

Maybe mitsulogger isn't calculating load right, anyone using evoscan?

 

i have tried rescaling mine with no effect so i put it back to stock

 

I use evoscan.... I dont understand why it doesnt see higher load. What is the formula it uses for calculating EcuLoad anyways? I think there must be something wrong with the calculation thats limiting the load the ECU sees. that could explain why the injectors aren't fully opening. The maf calculates load based on airflow so its gotta be something with it.

 

well i've been looking and the evo maf is around 360 g/s so my 215.7 g/s must be correct sykou. you need to change the endian value from big to little or little to big. pull up your maf size table and push ctrl+m, then click scalings. click on airflow16 from the list and then click edit. change data endian from big to little or vice/versa. then click ok. you should end up with the maf size being 215.7.

 

complink have you tried any pulls yet with a higher maf scaling?

 

i havn't changed it yet... i have been busy working on an essay for school but will try to soon.

 

Awe crap. That would seem like the problem then huh... Gonna have to try this weekend tho.

 

alright guys i got some good news. to start with, i rescaled my 440 injectors back to 385, and my latencies to 1.2ms at 14v and 1.896 at 11v and did a comparison run and was hitting like 14-15afr. then i started playing with the maf scaling between 400 and 1600 hz (refer to my earlier post on how to change it to show hz). Its now hitting between 11 and 12afr. so i think this would be the best way to richen up under boost. im probably going to keep richening it up using maf scaling until it is somewhat close to the numbers i have in my fuel tables and then just tune my fuel tables. i thought about increasing the maf size but then i realized that would be a universal change throughout all loads including idle and cruising, so it would eventually be corrected by LTFT, leaving me right where i started. its best to alter the flow where the ecu is in open loop. i have yet to disconnect my fmu so that might be interesting.

 

are yall able to log airflow or airvolume in hz, if so this is the thread on how to change the maf scaling table to hz on the left side
