No worries! This is all very interesting anyway ... I've always been calling the things "air mass meter", "air flow meter" does sound like a better description.
@James - Flo has a B200F with LU Jet and a lambda sensor in the exhaust manifold, so it's a tiny bit more advanced than LE ...
I think you are spot on regarding bodgery and power-myths. Stock internals often can take a lot if mapped propperly. My 300hp figure was solely a rough estimate for the 360 AFM - its diameter should allow enough air flow for that.
As there are some nice pictures of my 360CS-T in this topic i felt it was only fair to drop some info.
The Original car was built in 1987 and was sold as a "limited diamond edition" .
I started the conversion in march last year.Engine is a B21ET out of an '86 244Turbo.I didnt use the cilinderhead of that engine but the one from my Original engine as I was planning on running it on LE-jet.The turbocharger was replaced by a cosworth type watercooled T3.The Original ECU had some minor modificatins.The ignition is completly adaptable.I build in a piggyback wich can be connected to a standard laptop.....
Injectors come from a V70T5R(the white ones).The AFM comes from a BMW 535i(E34).As the BMW runs on Motronic that won't work so I asked a friend of mine to customize the AFM.Now al electronic parts of the Original LE-jet AFM are in it and it works very well.
The Cosworth T3 is a nice choice...much better designed wastegate that the regular T3. I'm planning to run a .63A/R version from a Sierra RS500 on my 360.
Also changing the injectors makes this sound much better. Have you been able to monitor the air/fuel ratios on load, perhaps with a wideband lambda sensor? Working with the factory management is possible, of course, but it needs plenty of work. It sounds like you've been having fun with it! Have you piggybacked the Renix unit?
Yes ,I've piggybacked the renix.This particular piggyback was designed to install an autogassystem.Costs about €80,-.That includes the device,interface,software and shipping!
The AFM explained....
I also put in a Folkrace Camshaft instead of the stock"T"cam.The stock "T"cam dies above 4500 rpm,the Folkrace cam doesn't.Before changin the camshaftpower came at about 2700 rpm so iI had a very narrow powerband.With the new one power comes at about 1900 rpm and it never stops!
I have a narrowband conroller installed in the car.A wideband is still on the "to-do-list"

Bart, how did you get through the epoxy? I'm very interested in what you've done!
(yeah, ok, the mk1 is cool...)
The piggyback is placed in the wiring of the flywheelsensor.So you don't actually do anything with the renix itself.A friend of mine helped me to get it working.The renix is very sensitive to interference so we had to modify a bit of the wiring of the piggyback.It has top insulated wiring to avoid interference.Like I said it comes with an interface and software so can adjust the ignition the way you want in severalsteps.So there 's not neccesarely only one adjustment from 0 to 6500 rpm.In that range its possible to have several settings.
Regarding the T cam...absolutely...that has to be the first thing to go! The lower spool point doesn't surprise me...lower back pressure from the larger turbo, coupled with a cam with characteristics more like one for a normally aspirated engine. The Renix-play has probably helped there too.
I replaced te cam last december.In combination with the injectors.I used to have the orange injectors.Now as I said I have the white injectors.
The cam I bought from Folkrace.se is not a cam that was made for non-Turbo engines.It actually was designed for Turbo engines.They make re-grinds out of existing camshafts.Check them out on Folkrace.se. They are not expensive but very relaiable.
Hi Bart.
How are you? The DLS dash clocks i bought of you were a streight fit
unto my 345, however the wireing is different so did not work but
it was well worth a try. I have since found the proper rev counter and
everything works perfectly.
Cheers Mark.
Thx James!
