I did try to upgrade a year or so ago. The flash software froze, and after leaving it on for an hour, I disconnected the cable etc.

But it worked fine after that?

Update;

ECU is repaired.

“it appeared the firmware files had been wiped”.

I’m just glad it’s fixed!

I have tried both the flash cable, a normal comms cable and installing software again on the computer. I think the ECU somehow misses the connection protocol?

I haven’t tested spark. If I can’t connect to the laptop, it’s pretty much useless in drag racing :D I drove last night to the shop and pulled the ECU, bubble wrapped it and sent it to DTA just now. If they can get I going it’s great! If not, I found a replacement box, never used with new wiring loo...

There is 5V on the TPS when turning on the chassis power and ECU.

I’ll fill out a returns form and ship it to England

Couple of posts in, computer with RS232 port. Tested both DTA flashing cable, and a non-flashing RS232 cable. I have the habit of leaving the comms lead in the car. Might be that the flash button has been pushed in while trying to get it connected, but not deliberate. Only thing I haven’t tested is ...

If you having trouble following our instructions just send it back to dta for testing, they will charge you. You could have killed it with some reverse polarity event? I’m trying as good as I can to follow any lead in trying to make sense of this. I haven’t swapped any leads around, so reverse pola...

The ECU has been working fine for years.

Is there 12v on pin 31 y/n
Is there ground on pins 13 and 14 y/n
Is there 5v on pin 9 of the sensor connector when the above conditions are y ?

Yes, 12V om pin 31
Yes, ground on pin 13/14

Have to check 5V “out” on pin 9

No 5V, no ground on fuel pump pin.

Is there a way in factory resetting, or is it time for an upgrade?
