Thanks

So I was wrong on the A9L2 base fuel table my bad, it is .8. Thinking I should copy that table over and see how it does leaning it out a tad. Do I just have to change the base fuel table or do I need to multiply the MAF transfer as well?

Dleach keep us posted on the pressure change I am for sure interested in the results.

When youre WOT, it uses the base table with no HEGO feedback. Assuming your maf is dialed in, simply changing the commanded fuel in the base table is all you should need. I would do a WOT pull logging wideband,Lambse and LTFT to see if its running where it is commanded. Assuming that is good, all you need to do is change the base table in those load/rpm values.

Ill let you know how the fuel changes go. I already modified the tune, just need to climb under the car and set base pressure to 60. I cant get my car out of my driveway for the next day or 2.. they just poured a new sidewalk that crosses through my driveway. Didnt want to leave my car outside until it dries so it will be a day or 3.

Ended up pulling my transmission to fix a hard shifting issue and to install a McLeod RST twin disk. While I had it up in the air, I changed the fuel pressure and loaded the new tune. I assumed I would have some MAF table inconsistencies which turned out to be true. At idle, it was off a lot more than in cells a few above it. Im assuming that is because the fuel was boiling in my rails while idling causing the inconsistent trims. I havent driven it yet since the initial changes. Ill know more in a few days.

Is this accurate?

To be clear, is the following correct?

"return the maf" = re - enter the MAF transfer?
"return CID" = SARCHG?

Could you explain "return TPS failure?" I've not seen any info on this.

search SP** and everything that needa to be updated when the high slope is changed

Injector high slope is the entire foundation of any tune
