So in our cars what controls timing and your A/F or has an effect towars the outcome??

Ill start---

Timing: Distributor, TFI Module, Spout, IAT Sensors, ECT Sensor.

A/F- MAF, IAT Sensor, 02 ensors

Plus the ECU controls all those..

What else M I missing?
 
ship your car over to me and go buy a toyota or something...it's the only way, man.

all kinds of little things...such as the fuel enrichment in the cobras, battery voltage, things you mentioned....

what in particular is your car doing?
 
It don't sound like it is in your tune as you said this has happened
off and on before.

First thing ... here is a long shot :D

If you have moved from t4m0 to j4j1 ........
You don't want different strategies on different switch positions
Make all 4 positions like strategies
That has caused weird probs for some in the past

I just thought of something about the latest Tweecer software .......

I've seen some say you can not use an option offered in the save tune
area. Its something like save only recent changes or entire file.
Sorry to be kinda uncertain but I've never seen any of the newer stuff.
The bug is if you don't save the entire file, you may experience file
corruption.

On the outside chance your tune has gotten corrupted .........
You could just use a fresh file with changes of only inj's and maf curve

If you are using 24's ..........
You could further simply and isolate things by loading a j4j1 and
reinstall your stock meter. Be sure to load this new fresh file on
all 4 positions.

That would mean you are running with a file that has had no kind
of modification.

All the above ideas are to prove the prob does not pertain to a bad tune.

Again ... I suspect it is something not in the tune :shrug:
