1G-GTE ECU question....

[Karma Supra]

Hi guys.... I mentioed a bit back that I have a Mines 1G-GTE ECU for my Rev 3 engined GA-70 supra....

I noticed on the side that there was a screw on cover with some kind of adjustment pot under it, I assumed it was some aftermarket Mines add on, and controlled either the fuel cut, or the rev limit....

However looking at my stock rev 3 ECU it has the same adjuster!!!! Does anyone know what it is???? do the earlier 1G-GTEs have it too??? No pics I am afraid as my camera is dead

pretty sure my Gen 2 doesn't...

Neither of my Gen2/Gen3 ECU's have this.

Never seen either on my gen 2.

Thats really Odd........ I'll try and get a picture up for you guys..... I'd love to know what it does!

Is your car auto? My mates r31 had one to make the shifts more aggressive or something.

[Karma Supra]

Nope definitely a manual, although I am told the mines ecu is for either......

Its not just me that though its a bit odd then

I checked a spare AT ECU fom a gen 3 that I have. It has one of these adjusting knobs....

[Karma Supra]

So its not something wierd on my car then!!! Any idea what it does? My stock ecu is definitely a manual one!

[Pube]

When I removed the cover I noticed there was a white mark painted where the knob was set to, only guess you play with the knob and see what it does

I'll double check my Gen3 ones later on. Perhaps I missed something, they're both from auto cars.

Thanks Grega.... that is exactly what I am talking about!!! (Damn I miss my camera lol)

I have never seen anything like that on any other factory car!


The toyota ddealership doesn't have a clue either (no suprise there then )

i've seen something like this before on a early nissan E15T (ET turbo ECU)
if you turned the dial around it actually put the ECU into diagnostic mode
it had two LED's to go with it though and they would flash a sequence which would mean codes
not sure what this is for though.
