Its an seperate system that works with 1-2 or 4 injectors depending on est. output. There is 8 adjustable pots. one for boostdepending, and one pot. for each 1000/rpm (1000/rpm - 7000/rpm) The system is well tested and have performed 420Hp from a B254 engine (marine 2,5 crank) with 4 injectors and original LH-Jetronic (1,9 bar boost). I recomend 1-2 injectors installed before the throtle for power output up to 360Hp and for more power You must install 1injector for each cylinder. The best manifold is the latermanifold but with bigger throtlebody. If You whant more information about Your systems capabilitys send me the ECUnr.

It turned out to be a bad TPS. I'll find a replacement at the j-yard. I will probably replace the O2 sensor also as the car was sitting for 4 years or so. It was very exciting to drive the thing out of the garage finally! The car runs pretty well considering sitting 4 years. Has decent power too. Leaks a little oil from the gaskets. What I need to do now is make a list of what to check/overhaul before hitting the road since the car has been sitting for 4 years. I would assume this: Change oil and filter (already have done) Change fuel filter (already have done) Injector cleaner with gas (how often, how much?) New timing belt Change tranny fluid Rear end fluid? New tires (old ones dry rotted) Check brakes (replace fluid?) All hoses All belts I welcome any other suggestions so I don't miss anything? Once again, thanks to all all on the list for bearing with my questions. Your advice has helped greatly. I have learned a little about FI in the process.

Date: Mon, 21 Jul 1997 14:52:08 +1000 (EST) Subject: Throttle body sizing Hi everyone, I have a 2lt twin cam and am considering rigging up a quad throttle efi manifold for it. Firstly, I will be using the throttle bodies from stromberg carburettors to save the pain of trying to fabricate a tb from scratch. I can get these in sizes up to 40mm (i think 1 9/16") at a reasonable price. The intake runners which will mount on the head, and hold the tbs, will be made using aluminium tube, the internal diameter of which i can get in different sizes quite readily. again, i could get this in 40mm, or slightly smaller, or even larger (i think 50mm od & 3mm wall gives 44mm). The 44 mm option would be a little silly, as the tb being 40mm would be a restriction (compared to the runner). My question is whether 40mm is too large for this type of engine. It currently gives about 130hp, and is my mild-mannered street car. Driveability is my main criterion here. Any ideas would be greatly appreciated. Bruno.

I have the addresses of the boost maps (There is two for some reason). I have created some 3-D surface graphs of these maps, which yield nice smooth surfaces which indicate that I am on the right track, but I can't quite work out how they work. My only method of testing is to burn eproms and try new boost maps, but this is slow. I have altered the boost by altering these maps, but have not been able to successlfully get the boost I want yet. I suspect that the x and y axis of the maps might be combinations of engine load, revs, throttle postions, Map sensor output etc, but testing to work it out is slow. Does anyone have an idea of what these axis might be? Has anyone modified boost maps in ECU maps in different cars, and has an idea of parameters might commonly be used for the boost map axis'? It is also possible that both maps alter the boost, or one controls overshoot, or anything!!
