This is gonna be a hard one...it is obviously not one of the big manufacturers, and it appears to have function. I have no idea what the function is, tho I would be curious. Can anyone look at the pins and tell where it is acting? How would I read the program? I am curious as to what this does.
It is not a FCO device as I was cut off at a little above 12 psi. What else could it be? The car is a 91turbo, manual...ran a [email protected] 12psi on a t3/t4. Any info would be appreciated....
NM.... he is exactly right..... some how that eprom is adjusting the signal from your airflow.... wow thats intersting... please anymore info would be GREAT!
Hmmm...the car is 4th hand, and the previous owners kept the car in immaculate shape...everything was professionally installed, and I doubt they would do such a hack job.
As far as more info goes, I don't know what else to tell you. The car ran pig rich, had stock FCO, and it ran really well. All MK3s tend to run rich at 12 psi or so, so it is nothing out of the ordinary. I am going to keep this setup while using an SAFC2...don't know how that would effect tuning in any way. Any suggestions? I can take more pictures? Any guesses on how I could assess the function of the chip inside?
Interesting point...when I checked the timing a while ago (before BHG), the timing was way off...in the upper teens. I don't know what the factory specs are, but I remember looking at it back then and wondering why it was so off....I left it alone bc the HG went anyway....
i have seen one before a long time ago. It is from a company in japan and isnt all that trustworthy. i have long forgotten the name of the company. At least it is not considered a good mod from the people I know in japan. Be careful if you keep it.
As mentioned above it seems to be an add on FCD.
A company here in Germany sells them in addition with a manual boost controler as "chip tuning". All they do, is screwing up the Boost and turn off the FC with this litte solder-in thing.
Umm oh , yes they remove the first cat too.
But they take an arm and a leg for this stupid (base) mod. About 940 $
So all winter I've been picking away at the 7M, and now it's a completely stripped block. Follow along as I rebuild it with tools most of you have around your garages. This is a regular rebuild of a 124k engine that blew a head gasket 20 years ago and the car was then parked near Mt. Rainier...
what is the best blow off valve in terms of sound. I like the HKS Super Sequential but i'm not sure if there any blow off valves louder than that. Let me know
Firstly, it's original, I'm the 3rd owner, speedo says 187k miles. Runs good, brakes good. Some power steering belt squeak.
Here's what I know is wrong with it and some parts are en-route already:
It’s got an oil leak or power steering leak, I can’t tell which probably both. Need to de-grease...
Ok I lost my key the first day I get my supra....Stupid yes I know
Hopefully I can save people some time and money with this post....I searched and didn't find any info on it in the forum's. I know a lot of you guys are going to think wtf kid supra 101 I knew this 10 years ago but this is for...
