    Thanks for the link Bill, haven't had chance to properly digest the information yet (day job stress) but skim reading it is rather juicy. If that page is correct about disabling boot mode flashing then that's a real shame. I was hoping to try and coax those dead cells back to life by repeatedly hammering them with 0xFF and 0x00. Definitely not guaranteed to fix the issue but worth a shot just in case. Also tempted to write my own reflashing program and put it on Github or something for...

    Tbh, if it's on the line between hot and cold, that should operate fine. Will still be worth trying to get it exactly right though. :)

    By the way it does sound like a mismatch gearbox to ECU issue I am just trying to exhaust all other possibilities. Before you start hunting and buying new parts.

    I also had an issue after replacing an auto box many many years ago, where the car would drop into limp mode as you applied a bit of throttle to it. With no load, very low revs the gearbox would go in D. Then 1, 2, 3, limp mode immediately. I had not followed the alignment process of the selector switch on top of the gear box when I connector the cable. It was close but not close enough.when I selected D on the stick. The gear box selector switch was slightly off. And it was this that...

    I did fix an issue like this on a friend's car. Similar issues but car would drive ok through all gears. Then it would drop into limp mode. Long store short. The input or out speed sensor on top of the gearbox. The one that sits in a recess. Had corroded. Due to water getting in there. The terminal had turned to green powder. And the signal failed. So Limp mode was triggered. Replaced the sensor and reteminated the plug and all was good. But this was on a known good working gear box.

    Definitely interested in those notes BCX - the more we all know the better :) I do not claim to be an expert as I know we're all just scratching the surface. I just dug out the FLASH1 and FLASH2 Z-TAT programmers I had and tried to write to the knackered 7202 chip; FLASH1 Z-TAT with its own software would attempt to program but fail at the negotiating baud phase, but at least lights up the Vpp activity LED so I know it's *trying*. FLASH1 Z-TAT with the FLASH2 software is initially...

    Sadly no such luck, this was attempting to flash a factory 7202 ROM image to a known-bad MH7202F (flashing dash lights / not booting) with the memmodel set in EcuFlash Version 1.41.2483 to MH7202F (doesn't seem to be possible to set it to the MH7203FA admittedly). Reading the ECU is completely fine, although the ROM ID is garbage, opening it in a hex editor I can see the tables are there. It's just writing that fails... J2534 API Version: 04.04

    Jeez, I blink and ALL THE POSTS! :D Lot to cover here, forgive all the quotes! Indeed - I too have been running the latest EcuFlash on Windows 10, but I have been running MMCFlash (for the 7201 / H8/539F variants) on a Windows XP Virtualbox VM. I may try shifting EcuFlash and EvoScan into that VM too and keep them there.

    get it welded back on. tig welding the aluminium is the way to go. but the turbo compressor housing need to come off to allow it to be welded. you might want to give them the Y pipe as well, so they can mount the broken bit on the Y pipe and the Y pipe can be pushed into the compressor housing so the broken bit is aligned perfectly to the housing. then the broken bit is tacked in place and the Y pipe is removed so the full heat of the rest of the welding can be done.

    if you have the broken bit of the turbo housing, get it welded back on. that is what i did after the first garage that ever worked on my first VR4 gave it back with a broken turbo housing. i have to add that i got the garage that broke it to fix it. no garage has ever worked on car since then.

    Yep, this is symptomatic of a bad flash - the ECU processor detects an invalid checksum on the EEPROM and doesn't boot up. When you flash the car, you're actually resetting the ECU and loading a custom program into it, hence why you can still start a flash process Sadly no, it needs to be the exact known-good flash that worked last time. Otherwise the checksum won't match. As Garry has said, we can support you with a ViPEC / Link ECU, between Garry and myself we've got 8 years...

    Hi GregorEST - as Garry has asked, is the car running at this point? The symptoms you describe are akin to EEPROM failure - it plagues flashing most factory ECU's at this point (which is why I keep spares when I'm tuning!). There's 2 types of failure I've observed; * Flashing failure towards the start of the EEPROM addresses, this results in a totally dead ECU you cannot fix * Flashing failure towards the middle / end of the EEPROM addresses, can sometimes be recovered by flashing...

    Hello! Definitely better advice on here than on failbook. We are good armchair shoppers, so if you find one you like the look of then post it up and we'll dissect it. Whereabouts in Worcestershire are you?

    As Tim says, that bolt can't be too long. If it is it will hit the casting sprue below the bolt and force the bolt hole away from the sprue. I've seen that damage at least half a dozen times.
