Old Dta race E4 fw 9.01

Post by MJPescos »

Got one old ecu with another one for spares, the spares ecu has pin code on it.
Any chance getting it open?
Does it support Dtawin?
Dtados did work with it but asking for pin, and the pin written on the unit with marker doesn't open it.

Any help would be appreciated. Was planing on using the case and connectors for something else and found out she still has life in her.

Anyone?
DTA forum and no one knows?
Another question, can the E48 control VVT solenoid does it have any other PWM output than the boost solenoid out?
And I mean is it possible to drive the VVT with boost solenoid output?

If you have a spare output, you should be able to control a simple solenoid.

Only way to know if DTA Win will work, is to download it and try it. Although you would need a pretty old version to try

This is the oldest DTAWin I can find on my computer, it seems to be from around 2001, it's a zipped file. Not 100% sure if it is the entire installation file though

Thanks man, need to give it a try.
Interestingly enough the E uses the same processor as the E48, so it should be possible to get it to work with the same software.
Need to dig up my old eprommer from the storage.

That ECU was sold in August 1996! Probably one of the oldest we've seen still running.
It will not work with DTAWin, the firmware version has to be V17 or higher.
I don't know if there is a pin override option in the DOS software, but you can try 2679.

If the VVT is simply on/off, then the E48 can drive it. I think the only flexible output is AUX2, so you would lose fan control.

Yes it's very old, need to test after the holidays. Have been way too busy for couple of days.
Thanks and merry Christmas!

Happy days, went the hard way.
Figured that the cpu is the same as in the E48 so burned eprom file from that one.
Booted the ecu with the new eprom and it accepted the read the code with the E48 pin tool.
Erase and reburn the original eprom data.
Tadaa the ecu is accessible again.

One problem, Dos software crashes when opening menu 31 Injector phasing and aux2
And menu 33 wont open at all - turbo control settings.
Interesting endeavor nonetheless, had fun playing with old tools again.

Had some time to function test the older ecu. Seems to work, well its built like a tank and through hole components.
Neat little package, might put it on my motorcycle or on a zetec engine.
Small video of the test.

Well done !

Did you try to see if the later Windows software would work ?

I was lucky in the windows software came out around the same time I got my P8, so only ever used the old DOS software very briefly.

No not yet, just had time to tinker with the unit. Going to test it today.
Edit,
Nope, needs ecu version 21 or higher. This is 9
Anyone got 21 or 22 firmware?
