i'm pretty sure you can use an OBD1 ecu in an OBD2 car with no problems, but not the other way without problems. the obd2 computer should have extra pin inputs that the obd1 wiring harness can't support.
woudl there be any problem using a 97-98 ECu in my 94 supra?
If you have details on the conversion I'd like to hear about them, one of my buddies just asked me about swapping his 97 auto ECU w/ a 94 that he just got his hands on. What modifications need to be made if any.
I can't see any point in swapping you ECU w/ and OBD2 one, that is basically the opposite of what most people would want to do.
the thing is 94 ECU runs lean...and frankly speaking I rather run rich than lean.
I now have 2 guys confirming with me that when they use 94 ECU in their 97 supras, both of their A/F jumps up to 13-14:1
I find it hard to believe its a coicidence...
andi's car did this but it was more then just the ecu causing it. a 94 ecu in a 94 should run just fine... ie. rich, but when you transplant a 94 ecu into a 97/98 to solve obd2 problems you get problems with lean a/f.
in other words, if you are hoping of solving a/f problems in a 94 with a 97 ecu, you are barking up the wrong tree.
MANY ppl run the pre obd2 ecu in their 97-98 cars. I know Noel Samael of Dallas has been running a 95 ECU in his 98 for some time now (he has a 730 rwhp to4r). I soon (in the next week) will be running a 95 ECU in my 98 too, hopefully no problems....
During my subframe restoration I broke both of my rear abs sensors. They were seized in the hub. It seems they are impossible to find in Europe.
I'm wondering if the sensors from another model fit the Supra. For example the sensors from the Rav4 and Yaris look almost identical in the...
Just traded for my first manual 94 Supra Twin. I checked all of the vin tags and confirmed it is a twin. My car does not come with the traction switch in the console. I'm not sure if the previous owner removed it or if it was an option for the dealer. Can anyone confirm if this?
I’ve been reading supra forums for months and months now. Love this page, and this is my first post.
I’m about to port my vvti head and I have some questions pertaining to the valve guides.
So, assuming my guides are within spec (it’s a low mile motor), what are your professional...
Note: Car was perfectly fine before it’s last wash getting it ready for a photo shoot.(engine bay was sprayed with water).
So I’m driving to the photo shoot location and I start noticing a misfire. The longer I drove it progressively got worse to the point where I would just get pretty good...
I'm having trouble removing the banjo bolt on the fuel pump assembly. Tried everything I could think of besides an impact wrench. Wanted to ask some folks if that was a good idea or not? I'd really appreciate any insight you can offer.
To be clear and avoid miscommunication I found...
