930 CIS from 86?

I recently acquired some "parts" from a track car. I was surveying a throttle body and noticed what looked like a tps. Does anyone know what this is? It is not on my 78 930. I have also discovered this motor was andial equipped. I also noticed there are some differences in the manifold and WUR. I didn't realize there were so many differences from a 78 930 CIS.





The fuel head has also been opened up, I am told. Is there a way to determine by how much? Injector flow test?

"Andial equipped..." What Andial equipment is on your engine?

The later CIS cars have a TPS of sort but it doesn't measure a linear curve like the ones most of us are familiar with. It is more like a 3 position sensor that measures closed\half\full throttle.

I can't remember what it is for but I'm sure someone smarter than I will chime in.

Sorry to be to vague. It only has the fuel enrichment processor and frequency valve in the parts I bought.

I had another car that had the f/e and the dial of death. That must have been popular back in the late 80's

The throttle position switch is part of the lambda emissions system switching it into open loop mode to allow a richer mixture at full throttle. Not sure what effect it has at medium throttle but probably changes the frequerncy valves return line percentage.

I removed all the lambda crap on my '87 and have wanted use it to trigger a relay that disables the AC clutch at full throttle but havn't gotten around to trying that.

Are you going to use it or sell it? I'm curious what you got it for.

I can see the Andial enrichment freqency valve, with of course is useless without the computer controller that goes with it. As Jim said, the TPS is for the Lambda system.

Jim,

This stuff came with a bunch of other 930 parts like a scavenge pump, turbo, i/c, engine tin, w/g, etc so it's hard to put a value on the lambda system. It seems any of that 930 stuff is getting harder to find and isn't coming up that frequently to gauge the market price of something. I am going to figure what I am going to keep for back up for my 930 and sell the rest to pay for parts for the 78 like window gaskets and so on.

Mark,

I do have the controller. It came with the jetronic lambda system. You are right the f/v would be useless and even better to have the controller than the f/v imho.

John

Unless you bolt an additional injector controller onto it and use it to trim CIS pressure under boost - like Thiery and Stup did.

Which was my intention when I bought the Split Second AIC1, until the debacle of Unwired killed all my appetite for messing with CIS...
