well, i finally got my ebay special MAP clamp....

the guy always seems to have them listed, so if anyone wants one, i they should still be available.
the install was not hard at all. the hardest part was removing the map sensor to trace the wires back to the ECU. you could just tap into them at the sensor, but there is very little room to do so. the MAP sensor has a built in temp sensor also, so it has 4 wires instead of the normal 3, which made it a little tricky too. the map clamp has 3 wires RED gets hooked to the 5V+ wire of the MAP sensor, which is a green/black wire. the BLACK wire hooks to the sensor ground which is a brown/green wire. (be careful here there are 2 that look the same. the one you need is at the very end of the sensor harness) and then the white wire of the clamp goes to the sensor signal wire. in this case it is a white/green wire. i then wanted to find these wires at the ECU harness. that was a little easier said than done ! there are about 3-5 wires that all have the same colors at the ECU. so to find the ones i needed i just used to voltmeter to check for continuity from my wire on the sensor up to the ECU harness. i didnt count the pins or anything like that, so if anyone else does this install, you will have to do it the same way i did.
the results....... well it works like a charm. i had to ghetto rig my volt meter into the cabin of my car to monitor the MAP voltage. i turned my MBC up to a point that i was gauranteed to get fuel cut and went for a drive. i found that that i would get fuel cut at 18psi which was exactly 4.13 volts from the map sensor. i then started taing voltage out using the MAP clamp. it didnt take much, a few turns and i was good. i now have it clamped at 4.03 volts and i get no fuel cut at 18-19psi !! i think by removing 0.1 volt the car only sees about 16.5 psi. which is really good. that lets the car see MOST of the boost that is actually there, and is only hiding a small portion.....just enough to stop fuel cut ! all in all, i would say this works great ! by far better than the ATP device which has to bleed out hard earned boost to work. my MAP clamp and MBC cost me $110 and it does EXACTLY what an out of the box standback does !! i will have dyno results soon. i go for my high pressure fuel pump soon !
