OK, I had a plug-in chip on my car, but took it off b/c I didn't know what it was for(was there when I bought the car).

It is from TPS-TEC, and the part # is G14E.(I can't read the name very well, but think it's just TPS-TEC, but there might be more after the TEC part). Oh, and I can't remember, but I think it was plugged into my intake near the MAF(I think it was something for the IAT, but not sure).

 

Post a pic.

 

 

 

Ummm, looks like a very big thumb or a very small lamp.

Guess: Liar module for the TPS - tells ecm that you are at higher throttle than actual in an attempt to get some timing and go open loop sooner?

 

 

So how would going open loop sooner help with my car going faster?

 

it doesn't. It's another $100 paper weight sold in the catalogs.

 

So does this chip do anything?

I'm not sure if it was the chip, b/c it only happened once then I took the chip off, but I was in limp-mode(it shifted at 3500 rpms, and not any higher). I took the chip out and reset the computer the next day, so I don't know if it was the chip or just something that day, b/c I drove it with the chip on for a few days after I got the car.

Oh, and does anyone know what brand, and what upgrade this chip is?

 

It's possible that this set a code and caused you to enter limp mode. This itme plugs in line with your TPS sensor. The TPS Sensor should have a voltage of about .54-.60 volts at idle. At WOT your TPS voltage should be 4.0-4.7 volts. In the stock chip, 'power enrichment' occurs at 70% throttle. Power Enrichment, or PE mode, is when the BLM locks at 128, and other fuel and timing tables kick in. This $100 gizmo makes the computer think you're at 70% throttle when you're actually somewhere around 40-50% throttle. If you're min voltage is too high, then this thing will make your WOT voltage even higher I guess... and in that case a code will set. I don't know about you, but the time it takes my foot to reach 70% throttle is not much longer than 50% throttle. For $100 I can learn to stomp the pedal faster. Most aftermarket chips make the PE change in the chip anyway, which makes this item useless. There is no brand name that I can tell on these things. They sell in the Mid America catalog for $99.99 each. PN 609-199 for 1982 & 1984 apps, 609-203 for 1985-1991 apps, and 609-205 for 1992-1996 apps. Page 139 of Catalog F11J.


hope this helps you understand what you have.

 

Thanks a lot man, I started doing a lot of searching and I came across it at ls1motorsports.com and read about it. You just told me exactly what it does, man you're good.

Well I didn't buy it so I don't feel so bad, it came with the car, I was just wondering what it did.
