Can anybody please tell me what this is? It is on a 1987 turbo 2, and it is plugged into the pressure sensor on the passenger fender. The fact that it is hooked up to the pressure sensor tells me this may be some type of DIY FCD, but I have no clue. This car was put together probably 10 years ago and parked so I'm having a hard time finding info on parts used. If anybody has any info on an old Superchips modded ecu, I would appreciate that too

 

It has all the components of a DIY FCD. They are just simple voltage clamps that can be made with off the shelf components. Just unscrew all the wires from the terminal block and match up the colors.

 

No expert needed...DIY hackjob...by someone who had no business near a car.

 

or who wanted to pop their engine.

 

well we can guess why the car was parked..10 years ago!

 

most likely...

 

Kudos for seemingly knowing how to use a breadboard and mount components like you know what you're doing, but major fail on using a screw bus bar like that in a car

I was a master installer in the mobile electronics space for nearly a decade and now an automotive electrical design engineer. I only once have ever seen someone do something like that, and the guy was an "electrician", which automatically qualified him to work on cars!

 

it's not a bus bar, bolted to the fender... but even decently built FCDs have killed plenty of turbo engines. the FC doesn't give much headroom over stock boost cut before the engine runs into territory it won't survive without supporting modifications.

 

I found out this was put together by the PO's friend, who is an electrical engineer, however I do not think he has any type of automotive knowledge. This car has a pretty fresh engine, it was just parked when the PO left it behind and moved away for college. It starts up and sounds healthy, but it is running rich. lol I guess the consensus here is that I need to ditch this thing and figure something else out, huh?

The car has 680cc 1st gen secondary injectors in it, and a superchips ecu in it. I think this car was put together in the late 90's to be honest, and the engine was rebuilt in the late 2000's right before it was parked. I cannot find any info on the superchips ecu anywhere, and am wondering if a Rtek chip would work with it. I have no rotary knowledge and am working with a budget and would rather spend money on suspension, but would like to make this thing as reliable as possible without going full standalone

 

you would be better off going with the Rtek 1.8 and ditching that FCD and this superchips ECU which i have never heard of before.

in the 90's there was a bunch of companies that had chips, they did little to nothing and were a waste of money. basically placebos where people's mentality was that they actually helped.

 

I haven't either. I spent about an hour researching it when I first figured out what it was, but couldn't find any info on it. I figured it's no good.

I already ordered another set of 680cc injectors to replace the junk ones that are in the car, but after doing some research I feel may have been a mistake. If I am correct, to use the 680cc injectors with a rtek 1.7 I would have to get a fuel controller such as an AFC, and they are too small for a 1.8? If thats the case, I may as well go with the rtek 2.0, and to be honest at that price range I would rather just find a deal on a haltech, run the 680's as primaries and get a set of 720's for the secondaries and take it to a tuner

 

This is one time where the slippery slope is a good thing. The RTEK is dead, I'm happy to see it slowly phasing out, and the cost of better solutions coming down is helping. Like many people, I started with RTEK and have never missed it once I moved on.

 

i wouldn't spend money on a 2.0, the chips for the stock ECUs are the only thing that i would consider a temporary bandaid, because they don't break the bank. once time to move on, buy a real standalone.

they had the ability to turn the 2.0 into something good, but last time i used one it felt more like a science fair entry than something i would pay to actually use. because it was not very user friendly at all. like the microtech, they failed miserably to step into the 21st century and just left alone what they had originally made, with only very minor improvements over the years.
