Update!!'. Tried using a manual ecu but no difference!!

 

Please help

 

 

Hi all

 

Really relying on you guys for some advice

 

Just installed a 2jzgte and w58 into a shell (also previously a GZ), and te car is only revving upto max around 4k rpm if revved gently, then kinda starts missing and feels like maybe a fuel cut or something?? If the throttle is pressed hard or blipped I get the same thing

 

Two things im concerned with is I believe the fuel return line is too small (didn't have originals) and there is a hks fcd pre-installed but not sure if on the correct setting and I don't have the manual.

 

Any advice would be much much appreciated, it's stopping me from getting ma project on the road.

 

Thanks in advance :-)

Auto ECU? If so you're gonna have to look at the neutral/park start switch. If its not done properly you can get a false 4k rev ceiling.

*As it happens I have a manual ECU if you get stuck*

 

yup auto tt ecu, definately connected the 2 black & black/white wires on the gearbox plug thing, still haven't done the reverse switch tho, would that make a difference?

 

And your saying of the connection is weak I may get them symptoms?

 

Thanks a lot Craig I can always rely on you.

 

And would the manual ecu work fine with a tt?

There's a certain way of doing the mod that removes the 4k safety rev limit. Yes it came from a manual 2jz gte car. That will remove all the auto conversion problems :)

 

well i havent heat shrinked yet but connections seem good

 

 

damn im kinda broke now but if you could pm me a price please

It'll never work right on an Auto ECU, don't bodge it, just get Swampys Manual ECU

 

I don't Believe that as I've had supra's converted before with auto ecu and manual gearbox including the 1jz engine removed from te soarer I bought from swampy :-)
