hey first off i really wanted to say this is an awesome technique, thanks for sharing. Second i got an error code 14: which is with ignition signal, diagnosis is no IGF signal to ECU... then it says "A" 7M-GE 6-8 which i dont understand, trouble area: ignition and ignition coil circuit, igniter and ignition coil, ECU. I also got trouble code 21: which is either oxygen sensor signal or oxygen sensor heater signal, So basically what im asking is can someone help me understand my trouble codes, and perhaps lead me in the right direction to eliminate my trouble codes, thank you.

Default Computerised Diagnostics

I wanted a fast car, one with heaps of ponies, I could'nt buy a 300zx, my brother in law has one. So I went one better, I got myself a 1989 3ltr turbo supra (completely stock, still has original air filter). Made him envious, as you can well imagine.

To get to the point, I'm wanting to bridge my laptop to the engine management (diagnostics). Is this possible? If so where is the interface port (PLUG)?

Will this work the same for a MKIV Supra as well? or is there anything different that needs to be done? Thanks!

I would like to know what years this works for as well, I know it works for all MKIII, I don't know about the MKII or MKIV.

Anyone?

Typically will be the same for all toyotas 86-95ish

Some MK2's apparently have some sort of diagnosis system but I'm not sure which ones exactly, it's apparently a 2pin plug with a cap on it that you short.

Default MKIII trouble code 26

This is a great forum/thread! I read through the previous 4 pages and didnt see anything on code 26 on 1990 turbo supra, and this code is not in the manual. Just bought the car a month ago and have been restoring it to stock. Everything has been going well until it started intermittently started cutting of all power under heavy acceleration. It always havens from about 3000you rpm and up. Anyone ever had a problem with this code?
