UK/Euro '99 Flash ECU Fuel Trims using Evoscan

[Marty K.]

Hi,

I am running a Jap spec GTO TT, with the Euro/UK '99 Flash ECU fitted.

It seems to work just fine, and I am currently running Evo560 injectors.

Problem I have it the long term fuel trims are not visible in Evoscan.

I have tried all the request Id's I can find for fuel trims and none of them seem to work on this ecu.

I get STFT no problem using id 0F, and my lambda sensor is functioning just fine using id 13.

I have tried (4A, 4B, 4C), (0C, 0D, 0E), (4C, 4D, 4E)

I either get 0 from them, which I know is perfect, but NOT going to happen!, or I get nothing from them at all!

I can only assume the UK/Euro '99 flash ecu is different in this respect, but I have not been able to find any other id's to try.

I could go through them one at a time, but there are a LOT of id's to go through!

Anyone got any info that may help?

Many Thanks

Marty

Are you getting any of the low/mid front/rear fuel trims registering?

[Marty K.]

No fuel trims are registering, apart from the short term.

Can you zip, and attach a log?

Sorry, I wouldn't know how to do this.
Nothing to show really.
I get no medium or long term trims at all!

Are you driving the car around for a while (30 minutes or so)? Low trim is pretty much around idle. Mid fuel trims take a while to update, and you have to be at cruising speed and light load. High fuel trims take even longer to update.

Yes, I have been doing this.

Doesn't seem to matter what request id's I use for the fuel trims. Still get 0's.
Is everyone here using the same id's I have posted above?
I realise I will not get any front's, as I have only 1 o2 sensor as it's a GTO.

Many Thanks

Are you using a chrome rom?

No. This is a euro 99 flushable ecu.
