Bear with me for a sec as I'm a bit of a newb.
I've recently picked up a flashable SMEC with RS232 cable ( not USB ).
I'm getting the ECU bootstrapped ( no fuel pump kick ) but the error I'm getting on the PC is:
Unable to download entire boot program from serial coms.
I've tried every which way that I can think of more than once..
Here are the processes I've tried to read it.
Click read, click ok, switch pin 11 on, turn key on, switch pin 11 off.
Click read, click ok, switch pin 11 on, turn key on
I'm running a jumper wire straight from the battery with an inline switch.
I've tried almost all combinations of baud rates and com port settings know to man.
MP tune knows when the ECU isn't in boostrap mode, it just wont talk to it the rest of the way.
I've checked continuity on the RS232 cable and its fine as well.
What am I missing?
