:-?

New problem as of yesterday...

After starting, will stall sometimes with clicking beforehand. Will start right back up (sometimes with clicking) then stall again. Battery icon will be on (but I think this is on when key is in ignition position w/o engine on?).

After the first few times this happened, I put in new positive and negative battery connectors (the stock were cracked/crumbling) and secured the battery against any movement.

Still happening... any advice would be fantastic as this is the daily driver.

Thx much,

Ecu would be my guess, the clicking would be the mpi relay turning on/off as the ecu dies and it loses signal.

Thanks Mech...Yeah - searching the boards info (ECU* worked) seems an ECUish problem... I'll be swapping in a 'spare' (wish me luck [-o< ) from a box of "back-up parts" that came with car. Photos of ECUs w/ #s below. What's with the upright; memory looking 'chip'? Also, the brackets although close, are different and off by a few good millimeters? Anyone know what the heck ECUs these are- I'm still trying to find Flying Eagles ECU list...?

just typed in the ecu in google..first site came up as.

http://www.chryslerecu.com/partindex/ecuoem135.htm ..... mods might wanan make this link a sticky..


Scrolling down to the 2 part numbers here is ur answer.

Aaah... good old Google! :wink: ... thx slowdsm!

According to that site the ECU that was in the car was a Colt application.
Now here's the good part - the 'spare' the guy included with the car is from a -
1990 Dodge D150 Pickup Truck (3.9-liter V6)?! #-o

Well here's the thing...
to keep things moving along between posting...
I swapped the board into the original housing...
reinstalled it...
turned key...
it starts/runs!? :-k
(Clicking/dying problem is gone also).

The the colt 1.5 million dollar question now is - what problems or harm can this wreak? :-?

Big temptation though. Can't- stop - myself - from - test - driving - it... 8-[
Will report back with damages/findings!

Updates soon,

The D50, aka the mitsu mighty max, also came with a 4g63t variant, which if you have a 4g61t, will work (but need some mods like injectors and maf).

If you scroll all the way down, you'll find the information archives (the one I reference in the "READ THIS FIRST" post at the top of this forum). When checking through the "Engine/drivetrain" subforum, you'll find the ecu # list post. ;)

So took a quick trip (a few miles, through all 4 gears) using a
MightyMax/1990 Dodge D150 Pickup Truck (Edit: 2.4L? {Orig referenced as 6 cyl}) ECU in the Colt 1.5 (!)...
(Non scientific/'seat of pants' test):

~About 1-2 seconds of low idle (then to regular) on start up.
~No Check Engine Light.
~Smooth acceleration.
~Filter box area seems slightly 'louder' on throttle now?
~Have not traveled far enough to guage fuel consumption.

Still concerned on potential harm/havoc running this setup? Any insight?
Possible electrical issues? Would the different sensor settings (e.g. knock sensor) affect engine longevity?

Much Obliged,

It's more likely that you're running the 4 cylinder mighty max ecu or that the ecu isn't labeled correctly/the numbers on it weren't read right. I don't think the v6 ecu would run at all on a 4 cylinder car.

Mechacode; All, Those are my actual pics above and the data is from that site provided by slowdsm. Even if it is (most likely) the 4 cylinder (which I think was a 2.4L?) I'm impressed at how well it runs (actually better - although my 1.5 ECU may have been last leg since I got car).

Update - Findings after driving 241 more miles:
All of the above plus,
~1-2 seconds of low idle on start gone - now = initial 40-50 sec of slight (500 to 800 RPMs?) up down idle.
~241 heavy foot miles divided by exactly 7 gallon fill up on d@mn near empty = ~34.4 MPG - so slight decrease on MPGs...
(was getting 36 and change w/ stock ECU - with tune-up 'in progress').

If anyone has a base model A/F spec - could probably test mine to compare?

Looks like this sucker is staying in for a bit (at least until repair/replace 1.5 ECU).

Banzai,

By the way do the spring clip retainers bend easily? For such a simple task, was a real pain in the balls putting it back in :headache: - there was NO way the ECU was lining back up with the bolt holes (with the Mighty Max board swapped into the Colt housing) - at least (most) got the ground bolt in securely...

Thx,
