Map Voltage and boost chart - SRT Forums

$PK$ · 10-11-2007, 09:18 PM

The link in the sticky is not working.
Can someone please post that chart that shows the map voltages and boost levels for stock and staged pcms. I just bought a mapclamp and I want to check it out. Thanks

Im talking about the graph that shows the stock/stage 1 pcm boost/voltage as well as the stage 2/stage 3 pcm boost/voltage. Its the one that is stickied but for some reason the link is not working.

go to post #14 in that post. There's a copy of the graph.

edit: oh hell, here you go.

that cant be right as im clamped at 4.28v and my map shows me 13.6psi

The graph that sour krout posted is for 2 bar. Our cars come with a 2.25 bar sensor.

yep, sorry. The original graph was updated to the 2.25 bar after that one was created. I don't know if I can find the corrected one or not. Good catch .

The first post tells you how to calculate it, you don't need the graph, just a calculator.

here, for the lazies that dont like to calculate...

i really see no importance in this chart tho. tune by KR and timing. at one point, according to the graph, my car only saw 7psi of boost due to my clamping. didnt tell me anything important for my sake of tuning... just something that i could say 'oh cool, im clamped to xxpsi'

it sucks that a 3bar map wont work on s0-s1. I'm maxing my little 2bar map the f'ck out!!! LOL

sure you can..its called SCT.

and whats wrong w/ the stock sensors? i had mine clamped down at one point, to the high 2.8-2.9v range. no ill effects.

How much timing and KR were you seeing? and what fuel were u using not to get knock?

low 40's. 0KR.
91oct cali gas.

now w/ a different tune, my car does 39*, and does 30-33 at redline. 0kr

650cc injectors. all in the tune. pretty much

lvlistchif · 10-21-2007, 06:35 PM

could my map sensor be bad when my car is off but in the run position and the voltage is reading .10-.15 with the car off???? i have a small crack in the sensor and im thinking its bad cause of the crack...

give me an example of your timing map through the RPM's ? that would help me out. Im also getting 33deg of timing at redline but below that its starting at mid 20s and slowly goes up.
