EEC-4 died a9l

Unread postby indyhog » Sun Jun 18, 2017 6:25 pm

Well my my fuel pump was not working and I think here's why.

Image
One of the capacitors was leaking anyway so my question is send this one out for rebuild through some eBay seller or find a used Cbaza or later ecu. Already have quarterhorse and 5 speed so do need to stick with a 5 speed ecu?

Just finish installing a turbo kit and this is holding back from getting to drive it for the first time. I would like to do electric fan in the future.

Advice appreciated

best bet would be to upgrade to a cbaza ecu, an auto ecu is preferred as it has more goodies but any will work

u can even go with the last of the eec-v distibutor ecus if u want to do a remote tune

Good to know, I will hit the pick and pull this week to see whats in stock. Generally it is well stock with Panther platform cars (even saw a Marauder there a while back) and Explorers.

Any particular one to target?

Thanks,

if u ever see another marauder snatch the ecu out of it as they are one of the only v8 ecus i know of that have the starter interrupt hardware, not that its a big deal but cool none the less

unfortunately none of the panthers came with a distributor, your only option for a distributor eecV is going to be the 96ish trucks

I think I want to keep it simple now just to get running again and not update to the eecv.

Does it have to be CBAZA? There is only a snowball chance in hell of actually finding 94/95 v8 mustang in the Pick and Pull (many v6's). So could I use a similar ecu out of a 95 truck(cbaz0) and apply cbaza Strategy + your bin?

If you want to keep it simple, why not try swapping out the 3? caps yourself before you do anything? Or maybe a buddy that can solder if you never have.

nope if u get a cbaz0 ecu ull need to run a cbaz0 tune as they are different enough

u could look for a 94 town car or crown vic and see if it has a cbaza ecu in it as most of them do, compare the hardware code, the tag on most are A4A1

85gt , I could swap out the caps myself without issue but, after seeing the burnt circuits I kind of just gave up fixing myself and wanted investigate other options. Maybe it is worth another look to see if its easy to repair.

Decipha, I will look for one of those as first choice but today remember a guy I work with went carb many years ago in his '95 so the ECU around somewhere, he'll look for me. Also if you want it I will keep an eye out for that Marauder ecu, if its there still there. From the pin outs list on your site the '95 Mark8 looks like an acceptable sub as well. True?

Thank you for your help!

Ah, did not know about the traces. If there's a pic included, can't see it here at work.

Decipha, what's special about the marauder's starter interrupt circuitry? Having got the wiring manuals for the '08 crown vic, it shows two flavors for the starter circuit. Only the police version has no EEC involvement for the starter. The rest have the starter relay ground provided by the EEC. Wouldn't this be the same as the starter interrupt you mention?

yep, its nothing special but if replacing one of them ecu's then you have to rig up the pin on the ecu internally where as if you have one of the ecu with the internal hardware you can utilize it as intended

Thanks for your help, Up and running now with CBAZA+TM42+ this unit snagged out of a 94 Mark 8 . Need get down to tuning details but it was overall easy with help from your write up. Heres a couple pics of the guts if anyone cares...just found interesting vs the old one. One last question before closing this, I had read some where that this is an 18mhz chip. True?

MHz is written on Y1A, just to the lower left of 8061 microprocessor
