What is the injector offset that your running? I'm wondering if i'm in the ballpark of the being right.

It's been a while since I've messed with mine, but mine are in the ball park of 42 (high) and 58 (low). However, I have adjusted the Injector Offset to allow for this... Otherwise a ran out of room on the low slop (>110).

What is your offset at 12v and 14v?

I would have to read my TwEECer tomorrow (got a wedding to go to right after work)... Keep in mind, the last time I adjusted it, I was having electrical issue that I didn't yet know about.

Cool thanks. I think we should have a sticky about the general consensus for popular injector sizes. Something to start out a basic tune with.

This is what i was looking for. I know jason had issues with his car, i had already asked him but i thought there were quite a few people running the 48 accel's. I feel like im close because kamrf values are pretty close to 1 but when i cruise down the highway at part to no throttle the car runs like 11-13:1 afr and i havent had a tank of gas that ive seen more the 14mpg yet. I feel like i should adjust the offset until i get the cruising afr correct and then lower my high slope of 48 to get the car to not be lean at WOT.

I was having the same problem. Especially when cruising in neutral. A/F went WAY fat. I took 30% off of the injector offset value from 12v and 14v. So far it really made a difference. No pig rich part throttle, or when I shift to neutral.
Start with -30%, and see what happens.

I have already taking 30% actually a little more off and it still runs like that. What are your running for slopes?

my 47.7 (or whatever they are) i got from tim i have set at 48/85 i think and it seems to work well. idle its lean (dont really car at idle lol) part throttle and out of boost it bounces between 14.3-15.3 usually. and when in boost it goes down to 12.5:1 and WOT in boost goes to 11:1 - 12:1 usually. and somtimes richer. i cant wait till i get megasquirt...

beat ya to it.. gonna be playing with it some here in the next week or so.
that thing is a whole new world.
people seem to have a hard time with the tweecer. if it wasent for the fact how much a pita it is to adapt the megasquirt it would be the perfect solution because the software is almost idiot proof it does all the work for you for the most part.
its as easy as setting up certain values and then telling it what afr you want.

also the features the thing has is amazing.

you can use the factory harness or even make your own.
dont matter what injectors you use.
i dont wanna go on and on but its probley the best bet for someone who is serious about tuning and such.

highly recommend if people dont mind spending the time adapting it to their car.
