well i'm really tired from last nights rally but in short , its highly modified gas flowed polished ported,cam,big valves,vernier cam timing etc etc .the le has been modified to use extra injector to vary fuel pressure which is by means of a dash adjuster. obviously the injection compaired to the carbs is no comparison but at the time with grp a restrictions you have to work with what youve got.....the carbs may well be coming off and the injection back on due to road rally restrictions[we want to travel south and compete with the welsh boys]and you cant have more than 2 chokes.....plus we are from the north and dont like to spend money on things like ms

its upper left of the keys. i have even fallen asleep while typing this and must goto bed now

Well I've ultimately bought the car to use on road rallies, which means MS probably isnt strictly allowed and neither are turbos, so I've gotta stick with standard stuff (doesnt has to be standard in a 360 though). What I'd like to do is find a cheap 940 16v and transplant the engine and mangement from that into the 360. but funds are very limited at the mo.

I've got a 2.3 laying around - if I pick up the engine at Petes I can make a hybrid out of the 2 to bolt straight in, so then if it doesnt work properly my current 2.0 can be put straight back in as it'll still be complete. And all I'll need to buy (hopefully) is a head gasket set!

I need to get this Powerdyn stuff working so I can at least roughly measure the difference changes make. Any one got the software I could nab?

Your hacked LE system will do the job a lot better than the stock setup - some of the guys in the US are using pressure switches, etc to fire extra injectors...and some just switch extra injectors on by hand (dodgy....seriously heebish!).

You could have a working MS setup for £300 (incl the wideband to tune it on-road) if you shop around, especially if you buy second hand. We just picked up an MS box for Ryan's car for very cheap. If you're having to go back to the EFI manifold, you might as well make the best out of it

You know, I started with MS installation, then came cam. I did go this way because carb was crap and price to get twin carbs, stock efi or MS was around same, not very hard to choose then

Basic idea when changing engine is to add more air to engine while maintaining air / fuel mixture, it is not harder than that.
Hard part is how do you know how much more air any upgrade will put into engine and how much more fuel is needed.

Also when doing bigger changes ignition map should be changed as it is affecting really a lot to engine, how it drives and how much fuel it uses, in worst cases also how long until it blows up.

Anyway I have found out that there is no point to get say 20% more air to engine at full throttle if you don't change fueling.
With Efi you can put adjustable fuel pressure regulator for small changes and it should be enough, however it is not optimal solution, but you can get more power out with that upgrade and price is 1/3rd from MS

Pressure regulator won't be too good with B200F as lambda adjustment is changing fueling, but cat don't like overrich mixture that will happen because lambda correction is not available always, just in certain conditions.

HI all.

As the talk goes, I have had a experience with B230, K-cam and LE-jetronic.
The experience is no good. The LE-jetronic was fine in urban / city driving, but over 60 mph (100 km/t), it was no good.
It ran fine as long as I was driving with the pedal to the floor, but when I was coasting (3/4 of pedal down and less), it leaned out.
Lumpy driving

NO GOOD.
Then I switched to MS (actualy I made my own MS pcb and all that stuff) and now the 360 GLT with B230 runs fine... Actually VERY nice.

Just a little reply on the K-cam, B19 and LE-jetronic talk.

Regards.
Peter

^ Agree with him, that is very likely to happen

It sits on parking lot with empty gas tank, maybe next summer runs again if I get money for gas

Currently it has factory default carb setup installed as I don't need to keep MS installed if I can't drive too much

Only because it was my 'practice board' where I pulled out a few tracks resoldering stuff and had to bridge them with wires

The mods I did on the LUjet when I switched from B200F to B230F with V-cam.
In the airflowmeter I loosend the flap ~3 notches, increased the fuelpressure from 2,5bar to 3,5bar and the car runs more then great.
Ok.....I should not forget the best mod........Bought me a new fuelpump.

Hi Dan P.

I had the problems on LE-jetronic, and not LU-jetronic.
The LU has lambda sensor, and this helps with the AFR.

I tried the AFM-notch-trick, but nothing helped.... then there was megasquirt! When you get through to it, it's really a nice thing to have.

BTW. How do you like the V-cam? Have you tried the K-cam?
I would like to know from someone that has compared the two cams.

Regards.
Peter
