try these.. this is from my 780's

665


3.816
2.184
1.416
0.960
0.696
0.480
0.360

 

Latencies are adjusted in very, very slight increments. +/- 0.010 or less. You mainly need to be worried about the 11v and the 14v since that is the normal operating range for the car.

 

What turbo?

 

Thanks I will give those a try some time.

I am currently using the settings bez posted in the OP, and it seems to work pretty well now i've leaned my fuel map out to suit.

 

I don't get ECUFlash to make changes in anything less than about 0.03x increments.

 

I have been messing with these PTE 880s for a while now, as soon as I think I got it, I drive it for a couple of days, and check them and they are way out of whack. I would like to understand if I need to disable closed loop in order to get the idle in check. This is my biggest problem. The Idle is like +7 and cruise is like -2. They always seem to be separted by 5%. I am starting to wonder if these injectors are messed up. I bought them used. Has any one seen this condition, and would you recommend new injectors. I have been making small adjustments to the 14v and 11v latencies at like .03 at a time. It does make the idle go down, but will these things ever get close. I have made 2 adjustments to the latencies already, resetting the ECU everytime, and the idle seems to be coming down, but now the cruise is starting to walk away from me. HELP>>>

 

OK I listened to Appauldd and scaled my maf. After doing the this the LTFT low started cycling. I think it was a combination of the cooling fans kicking on and and MAF. I smoothed the dang thing, and went to scale the injectors. Here are the settings:
PTE 880s
Scaled to 790
3.312
2.184
1.32
0.936
0.672
0.36
0.24

Idle = -1
Cruise = -3

I have been driving around for a day with these, and since I have the EvoScan device from Hamish, I can constantly see changes. I ain't moving nothing. If anything changes, Ill post.

 

evo082006.....Glad I was able to help out. Your trims are about as close as they are going to get. Great job!

They will adjust a little over time. This is normal so don't worry about it. You are in the ball park which is perfect.

For more accurace with the LTFTs make the EvoScan calculation this.....0.1953125*x-25 (From JSCBanks)

ok noob question since i already know it will be "yes"

but does scaling the maf really make a huge difference? and if so can someone PM me exact directions on how i could go about doing it...its converted to HZ i believe already (i was thinking of doing it but never did)

 

I see, thanks!

 

hey guys im having some trouble scaling my freinds denso 720. i used my own injector scaling and latency at first. after a few idle logs and cruise logs i noticed the car was running rich. i modified the scaling and absoutely nothing changed. i also changed the latency and niether fuel trimmed changed. i just came back from logging the car using a scaling and latency value recommended by GST motorsports... guess what still no change in my fuel trim logs. heres the wierd thing. AFR's and the actual idle of the car changed with every reflash... as expected. but when it came to logging the fuel trims as i said the values are stuck. fuel trim low is at 12.6512 and fuel trim mid at 8.9253.fuel trim high at 1.008.

 

is it an VIII ? ... probably going to have to reset the battery to get the fuel trims to reset

 

+1

 

I should note that my E85 scaling is 457 and trims are +/- 1%

 

i did it once but maybe u guys are right. ok i'll try again today.... anyone else have their #'s for denso 720's? will the battery need to be pulled for every reflash?
