Absolutely! it will be something simple and probably won’t be ECU but I will have to look again at getting it tested in near future
I’ve had very positive experience with Cartech Electronics in Cornwall when I had ecu problems on my Audi and they do Jags as well if that’s any help. Good luck!Absolutely! it will be something simple and probably won’t be ECU but I will have to look again at getting it tested in near future
See post #17Have you tried the ecu testing place I linked to in post #16?
Sorry to hear that. I would be very interested (for future reference)if you find someone who can sort out these Jag ones. I believe there is someone on the Isle of Wight?It was CARTECH that cloned my ECU I’m new to this forum and wasn’t sure if it is ok to name companies. Unfortunately I didn’t have a positive result my ECU wasn’t tested they don’t have the facilities. They took chip off my ECU and put it on another ECU. Unfortunately the “new to me” ECU had an internal communication fault leaving me with a multitude of additional fault codes. I do believe they are a good reputable company, but my learning experience now says have my own ECU tested and see if there is actually fault in it. Overall I lost 10 days and a couple hundred £ on ECU coming and going. Finding someone with actual testing facilitates for this ECU is a challenge I have called round a few people now.
Unless you do the basic SDD & pinpoint checks first I fear that you may be getting deeper into the abyss. Remember that, if you change the ECM then there is an automatic updating of other modules. That is unless you have found a way to configure a used ECM before fitting as per your original.Hi mark8jagman
tried the company on Isle of Wight “Avilec”phone is continually engaged I have been trying for a couple of days. However I may now have tracked down a used ECU fingers crossed.
I know of no 100% safe way of "moving" EEPROM. There is significant risk in the operation. You also have the problem that your original EEPROM could already be corrupt, so the copies will also be corrupt. There are many ways that this can happen, one of which is power interruption when the device is being written to.move my “memory” chips into the replacement ecu
The fault code is logged by the REM; which controls fuel the pump. The signal should come as a pulse from the ECM and the DTC P1235 meant that the circuit was either open or short to ground.On your REM fault did the ECU flag a fault code?
Having cleaned the ECM plug the situation has improved significantly, but I need to clean the intermediate connections as well. The P1235 code has disappeared and the hesitation has improved, but not disappeared.when you had default fuel pressure did your throttle body respond to pedal or was your car stuck at 1100 rpm?
I went for as test drive with the data logger on the Fuel Rail. I may have to rethink my interpretation of "default" pressure" as the majority of the time was around 380kPa, with the occasional small dip below and also increasing to nearly 400kPa coinciding with giving the car a little "gun". The hesitation is (almost) gone. Clearly I have some more contact cleaning to do, but the patient is improving. Maybe I should turn my attention to the Fuel Pressure Sensor itself.default "limp-home" fuel pressure
