95 16197427 PCM with 94 4l60e

[c5wagner]

So I currently have a 1227747 ecm controlling my 5.7l TBI 350 engine and have a 700r4 code MD8. The engine runs fine but I'm getting tired of issues cropping up with the 700r4. I'm pretty sure there is too much valve/servo bore wear, I'm also tired of improper TCC lockup and yearly adjusting the TV cable with a line pressure gauge. I want to move to a 4l60e and I have a non PWM 1994 4l60e, I also have the 16197427 BJYL PCM I want to swap in. Is there a way to remove the PWM stuff from the BJYL bin with TunerPro? I have a G1 moates adapter and can burn chips no problem but looking at the info:http://www.gearhead-efi.com/Fuel-Inj...Information-0D seems like all the 94 bins are actually for a 16196395 pcm checking on the BCC lookup. Does this mean there would be wire changes when using these bins? I'm thinking of using the BJLH bin.... Is there a 94 PCM that would be better than the 16197427?

By the way, this is for a Jeep wrangler v8 swap so the 94 transmission was chosen so I can re-use my shifter, adapter, and output shaft from my 700r4. The 95's had longer protruding shift selectors because of the neutral safety switch....

$E6 code will run on a 7427. Some of the ECMs lack hardware for the ISS sensor used on the 4L80E.

I've done a few 1227747 to 16197427 conversions, allowing a 4L60E to replace the 700R4. I'm thinking BFMF in the link posted above looks promising to use for the 5.7 TBI / 16197427 and 1994 4L60E.

Bluecat Transmission Table Software (see attached) is very helpful when tuning the 4L60E shift points: https://forum.hptuners.com/showthrea...Table-Software

Thank you so much! It is also good to know I can tune shift points with the 4l60e. Another reason I hate the 700r4 is the bad shift points because of my 4.88 gears and 35's. Always shifts way too early and at bad moments like crawling in 4wd low 1-2 shift when set to 1st gear. Even after messing with the governor weights since the TV cable has to be adjusted just right, it is still bad.....

Another thing I need to figure out is the VSS. I currently have a jags that run VSS that only puts out 2000 pulse per mile just enough for the 1227747 ecm. The 2 options I have found are http://www.dakotadigital.com/index.c...916/prd916.htm or a reluctor from https://jagsthatrun.com/products/par...ing-relocation. The reluctor ring seems like the better option because I wouldn't have to worry about low range vss issues for shifting

The 16197427 can also use a 2000 pulse per mile VSS. Where is the JAGS VSS located?

The Jags VSS is on my transfer case currently as I have a cable driven speedo. I thought I would have problems with being in 4wd low with it on my transfer case and I noticed the 16197427 has a second VSS input

I thought the f13 supposedly takes the 2000ppm, where the F12 takes?????? I'm also trying to get the 128,000 pulse per mile so I can also use the VSSB so I can get the cruise control figured out as well.
