Hi guys, Been a lurker on the Digest for a while, and decided I'd speak up some. :-) > | Under boost I have noticed that my car has a tendency to ping more at > | 3000 rpm , which I would guess is the tuned configuration of the motor. I don't know what kind of car you're driving, but I'd be willing to bet you have your EGR disconnected. That will cause knock at certain RPM (depending on car) even under light loads. The knock is caused by a lack of exhaust flow back to the intake which cools the fresh charge.

Hello all, I am new to the list, but like everyone I want to build a EFI for my car. I have read through the archives and I just have a few questions. I am also new to the Microcontroller world (Haven't bought anything yet, just a lot of reading) and the likes, so please bear with me. It seems that the MicroChips are the easiest to start learning on. Am I correct on this? I would like to update the program via my laptop, so which chip series might be the best? What books or software hardware etc etc would I need. I know a lot about cars, just not the electronic stuff just yet, but I am willing to learn. Any help would be apreciated. And if it matters, I am going to put the EFI on a 1971 Chevelle w/ a 498" Nitrous breathing rat motor for Drag Racing only, and maybe put the EFI on my TR7 when I drop the 5.2l rover v8 into it...Thanks!!

You have to call them @ MSD's main phone number, and request their catalogue through the mail. The catalogue is rather thin, but contains a lot of neat stuff.
