Hmmmmmm, that could be the reason for a lot of issues.
What did you do with the gtec 1?
I'm wondering if putting a gtec 1 back in will put it back to the map it is supposed to be running

it was in the car, in the glove box i think, but it was 100% in the car because i remeber telling you

Right, i have a chip in the car, but i thought you said that was the original.
Nevermind, i may try sticking that back in, hopefully it will go back to the original map

A tumbleweed moment in Dyno Demon as Ste reads this.

surely chucking ANOTHER resistor on top of a Unichip is just trying to get round a problem, rather than fixing it? Personally, I reckon you'll spend forever trying to sort niggly little issues.

IMHO, you should dump the Unichip AND the resistor and just get the chip properly mapped.

BTW, as far as I'm aware, Flea doesn't need the car to be fitted with a G-Tec2, as he'll write his own chip anyway

Go on, call Leighton - you know you want to......

Agreed, the unichip is just a "middle" man that intercepts the signals from the engine sensors etc & changes them to make the ECU think everything hasn't changed & vice versa....

Dump that old skool tech & have a proper chip written for your engine.

I know what i'd prefer

Did the chip fix it or perhaps the resistor?

back at dyno dynamics now as we speak, so will update later.

Bad days! I don't think this tuning malarkey agrees with me.

Went back to Dyno Demon today, armed with the GTEC1 that the unichip was originally mapped over, and a GTEC2 for if it all went wrong.

Steve installed the GTEC1 back into the ECU, plugged the old unichip back in, and did a power run to see where we stood. Mega Rich!

He then proceeded to try again to remap the old unichip. This time he could talk to the unchip, upload new settings etc,etc.

Basiclly after hours of trying, the old unichip would not map. He could create a map on his laptop fine, but as soon as he tried to upload it onto the ECU, it came up with comms errors again. We can only assume a faulty unichip.

My options by this point were to go to the new Unichip Q (£595). Which we had tried to map last time and had some degree of sucess. However, i was not prepared to pay that amount of money, especially when i knew Flea could do it.

I talked to Steve about my options and his words were "Take it to the guy from the club, it's a no-brainer".

We then dis-connected the frickin piece of crap unichip, and installed the GTEC2 into the ECU. Did a power run, and the result was mega-rich again. I was not expecting this at all, So i was questioning whether it could be a mechanical fault causing it to run so rich. However, as it was running lean on the dastek unichip Q, it must be a control issue!?

Anyway to sum up, 3 full days of mine and Steves time gone, and the car is still fooked!

Apologies for the poor graph quality.

Any observations are very welcome

Flea-i will be in contact soon!

If you do a power run immediately after resetting the ECU it will be mega rich. I've run 1.6 bar on a gtech 1 and still flat-lining at 10 AFR immediately after an ECU reset.

How long does it take to Lean out?
