MAP sensor and adapter

I didn't think our PCM could support a 2 BAR MAP? In the PCM they top out at 140 or so I think. Is that high enough to support a 2 BAR? Also, if you delete the MAF these things go into SD mode banging gears at full pressure. This is why tuning MAP in the 3400 is such a bitch to do. You will destroy a factory trans mount in no time. If the car is not banging gears, you are not in the right mode to tune it, sucks!

Not only the MAP table, but the spark tables get maxed out as well. I've got a post somewhere in this sub-forum that discussed that, I'll look for it....

See, thats what Im talking about. So putting a 2-3 bar map on the car is pretty useless. That's terrible that you have to give up power due to a limit in the pcm with that table. What you have in there about it carrying the final value is right. Once exceeded, it will just hold that value.
