M30B28 turbo distributor problem

Post by babisbabou »

Hello everyone, after reading this :http://www.firstfives.org/faq/throttle/throttle.html

and almost every FAQ in that forum i figured out that i have to use a non return valve at the vacuum hoses that connect to the distributor am i right?

I have an E28 with a M30B28 DIY turbo and after 4k rmp when on full boost(0,4bar) the car stops accelerating violently and spits fire and boom boom from the exhaust, i guess it must be that the boost retards the advance, any other ideas?

If by chance anyone else had the same problem it was caused do to extreme fuel enrichment, solved by tightening the AFM spring.

Glad you figured it out. Next step for you is to convert to MegSquirt. I'll be back on the road in about two months with my m106 TCD turbo.

I should mention that you should not use a anti-return valve on the distributor.

Glad the fuel worked out. Enjoy!
