Chromed ECU and Speedo Calibiration

[knights19]

Hi all,
I have a 3000GT motor in the back of a Rover Metro (UK) I'm building.

I have a Chromed ECU (though not in the car yet) and have been reading loads about setting it up. My first problem is that I will have to make a new wiring loom as the previous owner made a right hash of it and reading ECU pinouts from the 93 wiring diagrams often do not correspond to the new ECU pinouts. Does anyone have a full Chromed ECU pinout list?

Next question: Is there a way to calibrate the speedo sensor with Chrome?

I have no ABS to take a speed signal from and my gearbox is an uprated Ford 4WD box which I could probably update to a later Ford Speedo sesnor to provide a signal, but would need to match the signal to a speed.

I can't help with the Chrome pinouts, but I'll give you a free bump. That's a really cool project you've got there!

What I'd do for the speed sensor would be to use the Ford sensor and use a translator box to translate it to the Mitsu style signal (check the factory service manual for the 3000GT/GTO, I believe the signal is shown there)

Send me a private message with your email address, and I'll email what you need.

ECU doesn't operate the speedometer. That gets fed direct from the sensor on the trans.

I've just got the transmission back from the builder so I'll check to see what it has. I see Burton Power do an adapter to fit a later electronic sensor, that could work.

As I have no Mitsu speedo, I'll be using the Evoscan software to build a dash and would like to include a speedo. Can Evoscan use the OBD2 speed output from the ECU, or would that really only be CAN on later models?

[Greg E]

Yes EVOScan can show speed but the transmission sensor needs to send the pulses to the ECU like stock. One thing I never verified was if the speedometer reading was accurate in a 5 speed car with the Flash ECU. I'd assume it isn't meaning you might have to calibrate the log equation to match your true speed.

making it more complicated is that I'm running a Ford 5 speed 4x4 box connected to it.

but that sounds very complicated!
