Getting my wide band tuning done tomorrow and was curious about this.

If I tweak my MAF table, how much will I throw my WOT out of wack??

I've got my cruise dialed in pretty good but I'll be putting larger injectors in and then getting the dyno tune. I figuring I'll need to fine tune my cruise again after that.

Thanks guys!

Changing the MAF table effect by a constant factor (e.g. multiply table by 105) effects WOT. You could adjust below WOT by measuring WOT flow rate and not making changes once you get close to that.

Changing your injectors will also effect the WOT rate. IMO, it is unlikely the injector scaling you choose will be exactly the figure you need.

My advice:

1) Put new injectors in.
2) Set injector rate & MAF to get LTRIMs slightly negative.
3) After step 2, go the the wideband and fine tune WOT.

 

Thanks Ragtop, looks like a plan!
