Has anyone ever heard of/used something called a VPC by HKS. Vein pressure converter. I guess it replaces the AFM and is also able to burn roms for different sized injectors.

No one answered this one ?
VPC's are for the MR2 and Celica turbos. Do you have a 1st or 2nd generation 3sgte install ? (3rd gen does not have an AFM) You would not get too big a of a hp increase with a VPC with a stock engine IMHO, or even if HKS makes a cip for the stock engine ? Are you going to get a harness to plug in the unit, or hard wire it in ? They do work well when the replace the afm. Add a bit more hp at the high end. They require a bit of retuning too. A GCC (Graphic Control Computer) is a good way to adj fueling vs rom via knobs. Some people have had trouble with VPC in colder climates due to the VPC jumping thar air temp sensor with a resistor, so the ECU never sees a Hot temps, and neither does it see a Cold temp either. There are different chips for stock, 550's, 720, or you couold get a custom chip burmed for any inj of your choice If you know of a tuner and can get a dyno plot with a A/F graph. O r tune on thier duno would be Ideal. Regards; |

I had one in my Supra along with a GCC and an F-CON. It's not smoother than going with a stand-alone EMS but it gets the job done and you don't get fuel cut. It has an Idle adjusting button, and a few more, but the tuning is not very precise.
