Thumbs up Re: V8 Crossfire Conversion Diary

We still are resolving a few issues that are mostly related the engine sitting around since 2002.

You may all be wondering how we got it running?? Well yesterday we tried a few things with the DRBIII thanks to Ferris but we still didn't get anywhere. I don't think the DRB is required in this conversion. it is basically doing what the MB STAR sytem does but not as well and no Developer mode. We just got fed up with all this modern computer stuff and went old school. We checked for fuel and spark. We then jumped the starter which we had done before but this time we just let it crank much longer. Then it started! We still coudn't get cranking so Robert wired in a relay to activate the starter when the key is turned to start. While this will work we are finding that sometimes the engine starts right up and sometimes it takes too much time to start. We are starting to think we need to go over the power cotrol module again. it worked fine when the V6 came out so it is hard to believe it went bad but the symtoms are very much like the Mystery no start issue. It could also be a slight error in some of the coding strings we did. We spent most of the time tonight working on the now intermittant starting problem and didn't have a chance to resolve the missfire on cylinder 4 issue. The engine did get to temp and my dual fan conversion worked just great. Thanks again everyone for the support. Words cannot decribe how challenging this whole project has been. Keep your fingers crossed for the first video and drive report. It drives half as good as it sounds, I am in for a real treat. The Anza exhaust now has a much deeper growl. I am now going to go read the Mystery no start thread and see what i can learn. i also saw on MB world SLK guys having a similar problem but I am not sure it applies to us but they seem to have a common problem with older cars and they dry solder connections around the K40.
Hi Lantana,

Congratulations for your work, I'm happy that you finally succeed your conversion project, may be we can race our converted cars side by side one day . Now, there is a place for a twin-turbo ??

I noticed that you install MAF and injectors from V6 to the v8, but MAF and injectors are different : V6 is 124 cc/mn and V8 is 256 cc/mn, so if you are running with V6 injectors, missfire could happen from leak of fuel and non correct MAF values transferred to ECU. Injectors may have different colors (Green for V8 and Blue for V6 I guess).

You can find attached a file which can help you to know (cc/mn) of your injectors using its Bosh serial number (can be read on injector).

Could you tell us what's fault code from ECU menu on DAS?

Best Regards.
Karim.
