I just tried to install a VPC 2835 D chip in my car. This setup is for more fuel and a car with cams(I'm still running stock cams). The chip I had before was just a basic VPC chip....not setup for bigger turbos and more fuel. Don't know how HKS gave me this chip when I bought the whole kit, but they did.

The problem. I put the chip in...and for some reason now, I get a check engine light, and the car will stall if I don't give it some throttle. I tried to take some fuel out down low but it didn't help. It also caused my car to to pull too much from the battery? The lights got dim and I had to jump the car to get it started again. I have a Optima Red.

I reset the ecu before I put the chip in. The good news(somewhat) is that the car will run rich now that this chip is in. I was never able to get any kind of black smoke when I gave the car a little rev. Now I get a nice puff when I give it some good revs.

I put the old chip back in and the the problem(and check engine light) went away. I run 43-45 psi FP at idle. Is this chip too aggresssive? Or should I try the C chip? I'll be getting cams soon anyway once my lean problems are solved.

Thanks for any advice.

Well its good to see that you are making progress I guess. You sure the chip was for a 6spd vs an Auto etc? just a thought. Hope you continue making progress and get that car to where it needs to be.

Scott,
I would def try the C chip.
My car idled horribly w/D chip. Even with cams, you only need the C chip. You can compensate w/a GCC or SAFC for the cams when you get them. I can't believe in all this time, no one ever opened the VPC to check which chip was in there.
That was one of the first things I did, when I had a fuel problem.
I solved mine by redoing my fuel system completely though. Now it's 11.5 to 1 ice smooth to redline...

Good luck

Thanks for the response Roberto and Kevin. I think it was Dusty at the Vegas meet who suggested I check which chip I had...and sure enough, it was the basic chip in there. This D chip is way too much. I don't know why I'm getting a check engine light...especially since it's a G=force. I don't have a scan tool.

Hopefully I can get the C chip by next week and the Supra Gods will finally shine my way

Someone told me that HKS does not offer any upfraded VPC chips for automatic tranny. whats up with that?

It doesn't matter w/VPC chip. It's only marketing. It makes no difference. I'm running a "6spd" 720cc "C" chip right now. The VPC has no control of anything the tranny does, and controls my fuel system just fine...

I just realized i put the chip in backwards:doh:
I was told that would fry the chip.

Thanks for the help guys.

I have the 18B chip in my VPC. Is that correct for 720 injectors and single turbo?
