Hello All,

New to the forum. Doing a complete resto on a Roketa GK-32, 800cc. For the life of me I cannot find a diagram for this motronic Bosch ECU. Anybody have this? I tied my wiring in to existing engine harness but my issue is I have no IGN ON to the ECU plug. Please help!

Your Roketa GK-32 has a Chinese version of the Suzuki F8 series engine. The EFI may be close to what was found in the Geo Metro G10?

There is also this...

Motronic 07-04-06

From Wiki:

Quote:
This system was used on some of General Motors Family II engines(C20NE, 20NE, C20SE, 20SE, 20SEH, 20SER, C20NEF, C20NEJ, C24NE, C26NE, C30LE, C30NE, C30SE, C30SEJ, C30XEI). The system is very reliable and problems encountered are usually caused by poor contact at the associated plug/socket combinations that link the various system sensors to the Electronic Control Unit (ECU).


Some of these images and diagrams may help you:

Copy those links into translate.google.com to get the English translation of those Brazilian or Greek sites.

Thanks guys! I was able to figure it out based on your link PGH. Still need to finish up a last few details on the wiring. Looking for a substitute fuel pump and master cylinder. I live in so cal and have been to the Roketa.com warehouse but the prices are crazy. Anyone know of substitutes?

I have been doing this same research. Where did you find the correct pin out for this ECU? I have looked on the link PGH posted of the google images but have still not found the correct pin out for the ECU. Just pics of the ECU plug numbered. Does anyone have any help here? Its the same M1.5.4 Bosch ECU.

The Russian Lada automobile uses that ECU version - Try a search on that make of car. Use translate.google.com if your command of the Russian language is lagging.
