sooo i connected to my buddys $4000 snap on scanner... anyway it told me i have 2 CEL's - the same old crank shaft sensor one and a fuel / o2 related one.

I also noticed at idle i have 15 degrees of spark advance... is this normal?

Does a CEL change the way the engine runs on a manual tC - ive been tuning the car with the CEL on since I dont have a scanner myself... could this be why im running so lean?

Update:

Figured out that my Mass Air Flow map was not adjusted correctly - fixed that and am now retuning. Will keep posted, i should havea street tune done tonight.

How off was the maf voltage table ?

enjoithis

.5-.7 volts (out of 5)

I think it is because i was using the "C" map, the dezod MAF map has the voltage levels that i brought it up to.

UPDATE: Wired in the 2.2k ohm resistor, took it for a spin, runs nicely, still need to fine tune the fuel trims before i know any results. Will keep posted!

Mr_Meaty

I saw your post on the AEMPower forums...glad you got it figured out.

now, was it you that was saying the guys at RIPP tuned you and was AEM certified but said the Crank Sensor thing is F/IC related so he couldnt' do anything about it?...or was that someone else?

what wire did you put this on? was it in the pnp harness?

enjoithis

Mr Meaty - YES that is true, Ripp blamed the F/IC said he will never tune one again!

08Superwhite - 2.2k ohm resistor between the Cam1 MAGI+ and Cam1 MAGI-

aen

how do you wire it? could you take a picture for me please? im pretty sure htat would help me alot too.

Mr_Meaty

So that is 2 resistors on 2 seperate wires, right? One on the MAGI positive on another on the MAGI negative?

08superwhite

no, it is one resistor, you connect one end to the magi+ and the other to the magi-. it goes between these two wires

Mr_Meaty

OK, I guess I dont' know squat about eltrical, but wont' that short those 2 together?

enjoithis

If one was a 12v+ and other being a ground, yes it would. In this case since these wires are a mere signal the resistor only creates more of a "buffer" on the signals produced by the AEM F/IC (i think thats right)

But it doesnt short out because there is not enough current to over heat a 2.2k ohm resistor.

ed zachary.

Mr_Meaty

whatever...that's why I dont' mess with electircal!
