Finally having some fun with this. Put my ECU/patch harness in last night and it started and idled right away on the stock 99 ROM. Check Engine light on, but expected since my car has no OBD2 emissions equipment.
Went out to the car this morning and flashed Chrome 1.0.1 with the periphery2 table set appropriately (left periphery0,1,3 alone). That completed successfully and the car starts/runs. (I have not tested driveability yet.)
Now comes the fun.
Check Engine light is still on. I wanted to read the DTC to see what's going on. I cannot get EvoScan 2.6 to recognize my openport2 cable. "OpenPort2 USB Cable not responding. Try disconnecting/reconnecting blah blah blah." It is not even getting to the point of trying to read the ECU... the program can't talk to the cable.
The internet says to try uninstalling/reinstalling everything. Did that, no change.
If anyone has seen this before and can offer wisdom, please let me know.
Details:
Win7 x64
Programs installed to C:\ECUPrograms folder
Have tried EVOScan in XP SP3 compatibilty mode & run as administrator (makes no difference)
EVOScan 2.6 and ECUFlash 1.43
EVOScan connection settings - using defaults for baud/timeout. Openport2. MUT3 checkbox, and EFI is selected from dropdown.
Just did an uninstall / folder removal / reinstall and still not getting anywhere. Installed EVOScan first (tried connecting without ECUFlash installed, no luck), then installed ECUFlash again and still no change.
Thanks
James
Perhaps I am doing something stupid here? First time using any of this software...
Attachment 4341
Stopping on this for now, got other things to do with the car today. Hoping to have it together for a meet tomorrow. Really don't want to put the 91 ECU back in if I don't have to.
Really puzzling since I was able to connect with the OpenPort2 and flash the ECU but I can't get EVOScan to log it or read DTCs (or so much as connect to the openport2 cable...).
Code reading has been hit or miss from me. Starting and stopping the logger function and then reading DTC's has yielded the most successful results.
I can't even get it to log. The sceenshot above was taken after I hit the "start datalogger" button.
But trying to read DTCs using the button at the bottom gives a similar "openport2 usb cable not responding" error.
Frustrating.
Wish I had an older computer to try this on to narrow down variables. Everyhing I have here is win7x64 though. Thinking about installing xp mode...
Odd that you can flash but not use EVOScan. I am pretty sure I am currently running x86 Win7 on my netbook but will verify when I get home. Have you verified that your device manager is recognizing your Tactrix cable?Quote:

I was able to get the DTC through other means (remembered I have a BlackStealth LCD I am working on installing - took that outside and hooked it up temporarily.)
Throttle position sensor.
But I still have to figure out this EvoScan issue or I won't be able to log/tune it when more mods get piled on. :/
ok just hooked up my ecu with everything needed and trying to read the orignial file on the ecu it asks which mitsu were working with on the ecu flash
none of them work ...
but if i use evoscan it hooks up fine
what did i miss
saw the section on cant read /write to ecu nothing there

There's no point to read the original rom from the ecu. Download the version of chrome you want to change and update the values of it. I use 1.0 since I have a 99 sl ecu and don't need any of the boost control.Quote:
