Help please - laptop died during flash on Jeep XJ

[3barboost]

Hi, help please on how to do a recovery ?

I have a jeep XJ 1997 model with Jtec ecu, the ecu has been flashed many times getting the map and injector scaling close, then the damn laptop did a power save auto off 1 minute into the flash............................

How do I do a recovery, I have restored power to the laptop and tried to flash the self same file again to the ecu with no joy, the car has not been switched off and is on a trickle charger to keep ecu alive

Is there a secret tool / command set to do a force recovery ? the ecu should still be able to take a flash or any other ideas how to do it, what other toolset do i need ?


help please

if you have bench tools, you can convert hpt to BIN and flash to the ECU

Hi
Only have obd tools. including Genius Dimsport master

how would I change hpt to bin ?

think I can force recovery mode on the ecu

pretty sure the hp tuners tune translation is BIN to HPT

not HPT to BIN

[SultanHassanMasTuning]

yes, correct but there is tools to convert hpt to binary search on MHH

[3barboost]

yes and i have a file converted that way

ok so as to a follow up on this

if the laptop battery / power drops off during a flash, on this 1998 Jeep XJ just re power the laptop and begin to flash a file (I have now done this successfully with the same file and then the oem file) Laptop power is obviously on the way out as the life is unpredictable

you can key off the vehicle, recover the laptop and flash as normal - there is no need to panic and worry if the ecu is bricked (which is exactly opposite to what I have seen on other platforms, so good job on this)

HP tuners support failed to understand the question when I logged it and tried to make out that "laptop power" was a tuning issue - I hope an automated BOT is to blame and not a real human

I did manage to convert the HTP file to Bin but my master tool does not have the JTEC flash protocol, so the only way to recover was simply by using HPtuners as if nothing was wrong
