Re: LA3 Code call for OL Fuel help

My understanding is that the VAM is maxed by around 3k rpm (or nearly so) so it goes OL at that point and just runs rich. The only validation I have of this is the time I was out west with the higher speed limits my fuel economy dropped off a cliff. At 70 the car would get 30 mpg. Running 75 it was ...

Re: SAD disassembler progress

Realize that important sections that get used frequently (like interpolations) probably got written directly in assembly by the programmers as any efficiency they could gain gets multiplied many times as this chunk of code gets used so often.

Awesome. I had been researching doing this on my 95 Mustang GT (CBAZA) as I had them in my Thunderbird TC and found them to be fairly accurate.

Re: Why Did This Motor Let Go? Pictures Inside.

Nice to see another nutcase here. We're running a 1987 Mustang that was an ITB car in SCCA in a previous life. It now has a 2.3t in it. We've did 3 races with it last year (NJMP, Summit Point and VIR 24). We go to Monticello next weekend.

I believe that they are all the same, but I could be wrong. It would seem to me that there would be at least a couple different flow rates. I wouldn't use the same one on a 1.9l that I would on a 7.5

Re: Dialing in Spark without a dyno

If you look at the data a little closer you can get away without a knock sensor but you are pushing your luck. Methodology: Do your runs like you already did. The difference is in the analysis.

Re: Has anybody used the factory EEC-IV diagnostic tools?

They were legally required to have 1/3 of their fleet be OBD-II in '94, 2/3 in '95 and everything in '96. Hence why the '94 Mustang V6 were OBD-II but the GTs didn't go OBD-II until the 4.6 in '96. There is no datastream until OBD-I so you aren't going to manage to get data out of anything before ~'...

Re: What sensors needed for a 2.3 MAF conversion?

94 and 95 were change over years. In 94 the OEMs were required to have 1/3 of their cars be OBDII, 2/3 in 95 and everything in 96. The V6 Mustangs went OBDII in '94 but the V8 didn't until the 4.6 in 96. So the CBAZA are all EEC-IV and 60 pins.

The Jag V12s used 2 PCMs, one for each side. IIRC the early Ford diesel trucks used the Navistar/International controller to run the engine and an EEC to run the trans.

Re: 1993 Mustang 2.3L Turbo Swap

I could be very wrong but the MAF only needs 12V and ground. IIRC there is a signal ground that is separate from the power ground. IIRC when you first turn the ignition on the 12v is applied to the sensor wire in the MAF to burn off anything that might have gotten on it. That's why it has 12v to it ...

Re: "CRAIA" 99 CROWN VIC vs "CRAI8" 98 MUSTANG

The circuitry inside the ECU might be different such that it won't work correctly. Things like pull up resistors can screw you up. ie the 2.3t guys converting to MAF while keeping the 2.3t ECU have issues in that the ACT that's part of the VAM has a different resistance range than the standard Ford ...

Re: Idle Issues '87 Thunderbird TurboCoupe

I don't think it's the EEC, but I'll try that tomorrow (I have a spare in the trunk). I can't upgrade the EEC without changing the low impedance injectors. And I'm pretty sure it's a mechanical issue, I just can't figure it out.

I'll take a peek but you have to remember the L series is pretty primitive. I don't believe it has a DSDRPM, it doesn't control idle the way the newer stuff does. It only has a desired airflow. Spark is fixed at 25 during idle (it's not using spark to fine tune speed). And I haven't changed any of t...

Re: Do you think I could use a mustang v8 ECM to run a 4.9L

Mike Sitar (or one of his bunch) did that in the mid 90's. He later became manager of the supercharger group at Eaton. One of them also had a 2.3t with a supercharger (in addition to the turbo). Their main problem was that it wanted to make 30+ psi all the time. I would think the straight 6 would ma...

Re: Hard starting on e85

Below ~50F ethanol doesn't vaporize AT ALL so you have to dump a ton more fuel in. I would suggest starting with increasing the amount of crank fuel starting at 60F and ramping it up quickly below that.
