JDM ECU...HP Increase?
I have in my possession a JDM SVX ECU (and TCU), anyone know if it would give any gains in HP or Torque, when plugged into a USD SVX?

Where did you find that? I thought they very hard to come by.

Thought I might drop it into FrankenWedge(which is currently running a 95 US-ECU...) |
Re: JDM ECU...HP Increase?
Test it with your butt dyno :D

Re: JDM ECU...HP Increase?
I may throw it in to see if I can "Feel" any difference...I don't figure it can hurt any.

Re: JDM ECU...HP Increase?
I'll trade you a stage 1av1 for them. That will make your car faster.

Re: JDM ECU...HP Increase?
I'll Probably take you up on that Mike...

Re: JDM ECU...HP Increase?
My though was that the TCU would be extremely valuable to someone looking to swap in a JDM auto transmission. Especially since they are available and cheap. But even better would be to have someone reverse engineer it then offer it as an TCU upgrade option on their website. (hint, hint LAN) :lol:
Not sure if such a thing is possible, but I can hope! |

The JDM ECU maps are different to USDM, they are optimised for higher octane fuel. Like Nate said, no EGR. I've run a JDM car on a UK ECU which is similar to maps and didn't notice any performance difference. The TCU won't work properly with a USDM gearbox. Quote:

I don't recall, and Michael has them now, he might be able to cross reference the numbers to find out.

I've inspected the hardware of JDM, USDM and Euro/Aussie TCUs. The JDM and USDM are almost identical. The only difference is a couple of extra components on the USDM (presumably to handle the atmospheric pressure signal). I built some custom TCUs for Ron based on JDM firmware running on USDM hardware and they work very well. The Euro/Aussie unit is very different. They use the different speed sensor arrangement and don't work properly with JDM/USDM firmware. |
Re: JDM ECU...HP Increase?
Positive... Even with the JDM firmware loaded into the US TCU of mine, the forward speed sensor was not reading the same as the rear

I got the JDM ECU and TCU from Huck. They look to be 94 JDM units matching what Phil already has on his website.
