I just happened to stumble on this. Maybe this is old news. However, this sounds like it's a new item. Has anyone on here used it and/or has any feedback regarding use on an IS300?


"Powerhouse Racing is pleased to announce that it is the exclusive North American distributor of the MAP ECU (Manifold Absolute Pressure Electronic Control Unit)! This new piggy-back system is similar in function and design to the super-popular HKS VPC (now discontinued), however, the MAP ECU takes it one step further by allowing end-user programmability through Windows based software via a serial com port. This means that the MAP ECU can replace the HKS VPC, HKS GCC3, and any other type of piggyback fuel computer such as the Super AFC and AFR. Basic setup takes only a few minutes, and allows the user to set number of cylinders (1-16), type of air metering system, throttle position hi/low, and type of oxygen sensor utilized (if any)."

Yeap good find. There are similar products like this on the market. People only like brand names like APEx and Greddy but there are other piggy backs out there that are muuuuuch more complete including this one. Check out www.perfectpower.com Ive been using that for some time now on VW's and Nissan. You can tune via laptop timing and fuel with it very simple software and it works.

But, I thought this was like a VPC? Can it work with the IS300?
The MAP ECU works like a VPC plus has fuel tunning like a SAFC. The perfectpower has also timing control. I dont see why it wouldnt work on an IS300. I installed one in a brand new 350z which has trottle by wire and works fine both timing and fuel changes. The perfectpower that is. The MAP ECU should also work on the IS.

OK I've been looking at this for my latest project car. Unfortunately I dont have my IS anymore!! :cry: My question after reading about it is this: How will it know how to run the engine if you dont have a base set of maps to work from? The VPC uses chips this has none. It says that it will learn with factory equipment and then you can upgrade to aftermarket. Does this mean that you can hook it up with the factory MAF and then after it learns from that, swith to the VPC style temp and pressure sensor? I cant see how since the basis of this system is speed density. Wxman do you know anything about this since you are in tight with PHR? I would be very interested if I didnt have to come up with base maps to get the car to run in the first place.

Is this what you are looking for?
