<DIV>I have been thinking about this as well & don't see any reason why this would not work. if 0-5vdc was 0-1 bar is is not 0-2 bar. this means though that you would have to redo all tables that have reference to vacuum (& now pressure) & the resolution of the sensor is now going to be 1/2 of what it was. the only reason to mention this would be if you had a lump cam & it was going to be hard to tune in the first place. I think that i have convinced myself that for the next car that i am just going to goto a CPU that has the accommodation for the 2 or 3 bar sensor built in & tweak from there. I think that this would probably reduce the frustration.</DIV>

<DIV style="FONT: 10pt arial"><B>Subject:</B> 1227730 with 2 bar Map?</DIV>
<DIV><BR></DIV><FONT size=2>
<P>
<DIV>So I was curious and started reading what a 2 bar Map does. Basically you</DIV>
<DIV>get the same voltage as a 1 bar Map but the readings are actually double.</DIV>
<DIV>So what would keep me from using a 2 bar Map but with the 730 ECM and 730</DIV>
<DIV>code but tune what the computer now sees as 50 KpA to actually be the real</DIV>
<DIV>100 KpA. This would allow me to tune the setup to up to 14.7 lbs of boost.</DIV>
<DIV>Does this sound like I'm on the right track? The only thing left is doing</DIV>
<DIV>the VE tables and spark Map. This would leave me with all the functionality</DIV>
<DIV>as before.</DIV>
<DIV> </DIV>
<DIV>Would I be better to drop what the computer thinks the injectors are so I</DIV>
<DIV>could keep away from 100+ % VE tables or would it work better to make it</DIV>
<DIV>think the engine is a 11.4 L or something like that?</DIV>
<DIV> </DIV>
<DIV>DanT - Is this a good idea or time for me to put on the CSH? :-)</DIV>
