Rembrant Posted January 28, 2019 Author Share Posted January 28, 2019 Ok, I know this is off topic from the main purpose of this site, but on the recommendation of the owner, I am posting this for a number of you who prowl junkyards. I found yesterday that the engine computer I was going to use on my project (1986 Lebaron convertible) is bad, something is wrong in the board causing it to fire all 4 injectors at once, as a result I need to find another one. It needs to be from a 1990 or 1991 Chrysler product with a 2.5L turbocharged 4 cyl. engine and automatic transmission. I have a list of compatible numbers I can use: 4639246, 4639248, 4639250, 4672121, 4672125, 4672149, 4672161, 4672162, 4672163, 4672164, 4672165, 4672466, 4672520, 4672649, 4686592, 5234681, 5234791, 5235195, 5235225, 5235227, 5235249, 5235477, 5235613, 5236479, 5276347, 5276349, 5276371, 5276373, 5276383, 5276392, 5276399, 5276407, 5276409, 5276411, 5276413, P4529998, P4529999 The last two are probably unlikely as they were Mopar Performance ones. Thanks for any help on this. I am hoping to get to the junkyard this week (weather permitting). I'll take a look around for you. They are surprisingly organized there, so if they have any of these cars I'll locate 'em pretty quickly. Unfortunately most of the stuff in the junkyards here is in the 10-20 year old range, but you never know. Link to comment Share on other sites More sharing options...

Problem I have, I don't want to buy a reman one as I have to modify it to allow the calibration Eprom to be replaceable. My car has a 2.2L turbo II engine which uses a different spark curve, more boost and as a result different fuel map. The 1990/91 2.2L turbos were what is called VNT, for variable nozzle turbo (same concept as the ecoboost turbos) so a computer for those is looking for a pair of solenoids to operate the nozzle actuator. The other issue is sort of like Ford's EEC systems, EEC-III, EEC-IV and EEC-V are all different systems, EEC-III is a royal PITA to test, EEC-IV is straight forward, but to modify the programming requires and add-on board, EEC-V is OBD-II compliant and is reflashable through the OBD-II connector. Chrysler went through 4 different ECM styles between 1983 and 1992, a two part one with the "brain" inside the car and the "brawn" underhood, a single module that still incorporated two separate boards, again "brain" and "brawn" and finally the single module where everything was on one board, followed by an updated version in 1992, to accommodate the updated steering column with different cruise control function switches. The first two systems bank fire the 4 injectors, 1 - 2 and 3 - 4, the latter ones are sequential due to more stringent car emission regulations. Thanks for your efforts, I have one in unknown condition on the way for $40 + shipping, if it doesn't work, I can return it for a refund. Link to comment Share on other sites More sharing options...

Is this the same or similar to what is used in the trucks? I have no use for the thing but can grab if anybody has a use/need for it. Link to comment Share on other sites More sharing options...

I'm just a lowly single tank guy, so I don't know what goes with the dual tanks. Link to comment Share on other sites More sharing options...

That is probably this one: 86/ E150/350 E6UZ 9A050-A #E6UB 9A050-AB - 6 terminals-mounted beneath instrument panel The "86/" means it was used at least until the end of the catalog, which was '89. But only on the vans. Link to comment Share on other sites More sharing options...
Rembrant Posted March 2, 2019 Author Share Posted March 2, 2019 Finally, after a year and half I found one of these elusive modules (locally) for a good price. Simple mind, simple pleasures! Link to comment Share on other sites More sharing options...
Gary Lewis Posted March 2, 2019 Share Posted March 2, 2019 Finally, after a year and half I found one of these elusive modules (locally) for a good price. Simple mind, simple pleasures! Congrat's! That's an easy, but very worthwhile upgrade. I was driving Big Blue thinking "I wish it had delay wipers" and then tried turning the knob counterclockwise. Sure enough.
