installing 880's tommarrow and....
I got the injector thing figured out. But the MAF scaling is freaking me out:crap:
The MAF scaling table is the one I need to adjust right? The highest the scale goes to now is 237... am I looking at the right thing? |
No, you don't need to touch the MAF scaling at all.
All you need to adjust for new injectors is the injector scaling and voltage latency. Eric |
what do you do with the voltage latency?

No, you need to rescale your load axis, especially with the 35R. On my little stock turbo cams and stock intercooler piping at 22 psi of boost on pump, I hit 300-310 load around 4800 rpm and it drops to about 290-285 or so for the rest of the rev range.

you're going to need:
extra load columns rescale the injector cc tweak the injector latencies tweak the AFR and timing maps |

I got the 880's in today!
Is it just me or do Evo injectors SUCK to install:mad: I scaled them to 750 and got the battary latency scaled as well and A/F is perfect I have also decressed timing a few degrees and leaned the fuel out a tiny tiny bit. Cruising I get 14.5 to 15.0 A/f and under WOT I have 10.6 to 10.8 A/F and show zero knock counts on 94 at 22 to 23 psi. 7500 rpm is as high as I will go. I think I need to scale the MAF but STILL I cant figure that out:crap: |
sounds like you've got a handle on it.. congrats

There is NO need to scale your maf! I don't know what you've been reading, the maf scaling thread has more to do with aftermarket intake adjustment than anything else. Your car has pretty much completely changed hardware, your tune will completely change and the intake will be accounted for in your tune. Forget about the maf!
Did you get the load axis scaled correctly? What did you put in the top bin? Which load bins did you delete? the numbers across the top look like this, across the top of my high octane fuel map screen... 10 20 30 40 50 60 70 80 90 100 120 140 160 180 200 220 240 260 280 300 is this what needs raised into the 340's or maybe 360's? |
that's what he's referring to, so how did you manage to get 20 columns? typo?
let the logs be your guide, if you're seeing loads in the 300+ then it's time to think about reconfiguring the columns to support it. |
As Mellon stated, use your logs as your guide. I'm scaled to 300 and even with occasional bumps up to 310 or so, there's no problem or timing pull. I'd imagine you'll be fine for now if your scaling goes to 300.
