Trust me, doesn't have to be done immediately

At your leisure. I'm curious. Gotta dig through the EVTM a bit more myself....

Would an 83 CFI have a VSS? or is it purely cable?

Trick flow heads and intake, Ed Curtis custom cam (230 duration at .050" lift max lift .565), 24 pound injectors set to 48 psi, 255 lph pump, 70 mm tb, 73 mm mad, 3.45s, 2800 stall converter, AOD with Silver Fox valve body. Wot shifts are at 6200. This car is the reason I supercharged my Mustang. Will pull on a new 5.0 Mustang without issue.

You and your light car :flip:

With 600lbs extra weight mine will pull on 3.7 Mustangs, 3.6 Camaros, and 5.7 Hemi Charger R/Ts and 300C Chryslers. I think I need a 363 or 408 to pull on a new 5.0 Mustang or Camaro SS.

Nice man! Sounds like it should be pretty stout!

It's fun!

After conferring with Joel 5.0 over @ SBFtech.com concerning this and why I do not receive a code 29 he stated the following:

Quote

You either have a faulty ECM or a wiring setup that doesn't provide 12 vdc all the time to pin #1 (KAPWR) causing the ECM to constantly reset itself and erase anything logged under CM code failures.

Makes sense I guess. I've had other continuous memory codes over the years though......
I went out to the car about an hour ago.

Here's what I got.
Computer removed, battery hooked up, and ignition OFF: 12.57v @ PIN #1

It gets interesting......
I decided to do a KOEO test with my tiny code scanner with the engine cold. It was sitting for approximately 7 hours.

The results: 54 (expected at ~70 deg. F), 95. The codes repeated as expected. I then received the single tone separator from KOEO codes to CM codes followed by a pause. The scanner blinked 95 twice then stopped meaning I have a code 95 in continuous memory.

If pin #1 was losing power with the ignition off should I not see a code 15 as well?

Well I know code 15 is KAM failure, it's possible that the KAM is good but not able to store anything if it's resetting itself......if that's even the case. I'd doubt it.

Like I said before I did get a VSS code a couple times after driving, but the battery would be disconnected for a few days, get it together, drive and the code wouldn't be there. Curious!

Figured it out!!!!!!

Took the car for a spin. Apparently the trick to pooping the code 29 is to get the car over 40 MPH or so. I got her on the parkway and brought her home. The 29 was there in continuous memory. Guess I'll be installing the VSS wires and fuel pump secondary wires tomorrow!

Even more infuriating was the code 54..... I JUST replaced the ACT for this because I logged a 54 the other day on both KOEO and Continuous Memory (I didn't bother with a KOER -- the ACT sensor was in the car for as long as I had it and had been on 2 different intakes, 2 cam swaps and a bottom end rebuild. I never changed it. I may have been original to the car). Reset everything and ran it afterwards and nothing. Today it's there again in continuous memory, but NOT in KOEO OR KOER.......

My car's a c*nt......

Don't even bother with the fuel pump secondary wire. I've never run it with no ill effects. Do run the VSS wires however.

I just want the stupidest code ever removed from the system.

I just live with the code 95. We've become friends over the years.

Ha! I do too!:p

Well I went ahead and ran the wire for the fuel pump relay voltage monitor this afternoon from PIN 19 to the relay wiring (pink with Black stripe). Easy to do with the only irritating thing was having to heat one of the seat back Torx bolts with a torch....I think the bolt became "one" with the car. :rolleyes: Anyway ran the wire under the door sill and carpet, behind the side panel and into the trunk and spliced in. Probably didn't have to go that far back but oh well. Everything checked out and seemed fine, I wanted to run a scan but didn't have the reader with me....tomorrow!

You did it the correct way. I got nothing accomplished today. Driving rain and 40 degrees. That and I'm waiting for parts the were SUPPOSED to be here today...... Still 1500 miles away. Awesome....

This thread confuses me. I never ran this wire, but never received a fuel pump code. I had I think 2 codes for smog, which I simply fixed by setting the thermactor-present scaler to disabled.

Anyone know why I don't receive this code? 1988 Sport.
