Corrupted Boot Program MPTune
Hey,
i am trying to bootstrap a SBEC II from a 1993 Minivan (Chrysler Town & Country).
I have the FTDI Cable set up and use inverted logic. I use a breadboard for chaning the wires back and forth for bootstrap.
I have another 1995-Model SBEC II which i use for testing. It works fine, i bootstrapped it and got the Code from the EEPROM three times to make sure everything works.
Using exactly the same method as on the 1995 SBEC II, the 1993 SBEC II will not work properly. MPTune gives the Error "Corrupted Boot program" or something like that.
Here the logs:

I understand, the Serial Com seems to be messed up. I added a 1K OHM pulldown resistor on both TX and RX. Still worked fine on the 1995 SBEC, but not on the 1993 SBEC. My Battery delivers 13 Volts.
Any ideas?

Re: Corrupted Boot Program MPTune
would you post up the 1995 logs? i didn't think any of the sbec2 ecus would work! the code needs to be updated i believe based on some input i received from another user.

I have another SBEC i read, from a Plymouth Import. The Part Number is 4686899. It hold a Copyright from 1993, although the verhicle is from 1995.
The ECU i want to read has the P/N 4686276
I have send both .bins to you via eMail some time ago.

Re: Corrupted Boot Program MPTune
It worked!
I was fiddling around with a friend, he was controlling MPTune and I was switching the Wires around. I had two successful reads, but comparing them in a HEX-Editor showed they were different, so the reading was bad.
I removed the resistors and was able two read 5 times successfully. All .bins were the same, so the reading was good.
I charged the battery last night, maybe that was a problem.
The ECU has a pretty bad looking Capacitor though, its overall condition seems to be a little rough. It also sounds different than my test-ECU when powered on. The high pitched frequency is much louder.
The Code holds a Copyright from 1991 and has little differences compared to P/N 4686277.
Cheers

Re: Corrupted Boot Program MPTune
great. glad it worked. there are a couple things that look a "little" strange but the program was able to work around it.
would you resend to mterveen @ yahoo dot com both bins you read, i.e. the 95 sbec2 and the 93 sbec2. eventually i'ld like to disassemble them and look at them. also note engine and transmission type.
thx.
