Post Need some info from anyone with an Autothoruty MAF and AFPR

Any idea about what I should have my fuel pressure at?

I had 2.9 bar with k27/6, maf, open exhaust and stock injectors. Turned it down to 2.6 with 55 pound injectors.

Special tool:

No offense intended from me resulting from our earlier discussion.

Now my question: Did you change the settions on the DME when going to 2.6 with the 55 lb/hour injectors?

Do you mean the timing settings? I didn't change them. I don't have Guru chips - I only have custom Autothority. Both of those fuel pressures are with cis guage at idle. - Jim.

Jim:

The DME can be adjusted as far as I know. There is a way on the DME to do that.

[quote] It looks to me as if those are generic settings and not only for the guru chips but I may be wrong.

Those settings are for the Guru chips only. APE chips have their own settings, I posted the values in another topic on the list recently.

*eurospeed951* if you and the car are up in the DC area now, email me if you are interested in custom chips for your 2.8L APE MAF setup.

"Any idea about what I should have my fuel pressure at?"

Look at your dyno-chart. Find the leanest spot and adjust your fuel-pressure up or down so this leanest spot is around 12.5:1 (gives highest combustion pressure). Changing your fuel-pressure will adjust your entire fuel-curve up and down as a whole.
