" Charter: This mailing-list is *strictly* dedicated to the discussion of topics related to EFI design and modification. I would like to see discussion on control algorithms, hardware, electronics, and sensor/sensor-interface designs. Additionally, modification and adaptations of OEM ECU's would also be welcomed." All this personal slanging is filling our discs with rubbish, by all means carry on but do it privately and leave the rest of us out of it!

Anyhow, after receiving very little useful information from a friend at an OEM we basically cam to the conclusion that you should take out about 5 degrees of vacuum advance. This is just an estimate. I would certainly make sure that I got the best performance possible at WOT and then retarded spark with the vacuum advance until I knew there was no knocking. You shouldn't be getting into the vacuum advance at WOT. Well that's my thought for the day. I'm going back to bed.

Check out Distributorless Ignition System ( Build your own) at http://spbted.gtri.gatech.edu/hpe/ddis.html. It gives a design for an ignition system using a 68HC11, which is reprogrammable on the fly and gives real-time data back to the host PC.

Maybe Haltech?? > > Maybe from someplace this side of the pond (Europe-Sweden)? > > Thanx in advance > Lennart Well...I do know something. I know who knows... I rebuilt a 13b rotary a couple years ago - mainly because I found a used one for $50 and I really wanted to understand the innerds. Anyway, I linked up with a company called "MazdaTrix" out of southern California. These people are experts, and they will talk your ear off! They advertize in the magazines - look for them. They sold me a new center section for my engine, with bosses for injectors right in it. Injectors are expensive (~$500 for 2 - never figured out why). The way it is supposed to work is the injectors only on the inboard ports, and the outboard ports carry only air. They have a race car that is set up this way... Look for a junkyard OEM setup. these are fast cars, and mangled ones are common, as are blown engines that were never repaired (EFI still good) Good luck. ------------------------------ From: "David Randall (SMS) (Volt Computer)" Date: Fri, 15 Aug 1997 13:09:55 -0700 Subject: RE: EFI on a rotary engine (correction) Oops..

Some have a seperate shielding box inside, so i would use the gatters, flipflop and resistors as smd parts. It is easier to use a 27C512 eprom when only a 27C256 is normally needed and switch from the lower half to the upper half (or do it with 4 sections when a 27C128 is standard) because of the same ammount of pins. The additional parts are only necessary when i want to switch under load; that is the real comfort.

If it is anything like their other products, it should be quite good. It should be on the engine dyno for tuning on Methanol next week.
