You might want to change you "Other EVO 8 ROM's" to add the tables and change the scaling values to log boost correctly. I was reading it and it was a little missleading to me as plugging it in and going did work but threw a code, but it did not read the correct boost settings until you gave me the tables to update the scaling values. Then it seemed to work. Do you think you should put that in there?

Very good news: I have found the tables that need to be modified in the '03 and '04 Evo 8 ROMs to stop the P1400 CEL when using the JDM MAP sensor. This may spill over into the Evo 9 ROM mods too. Its going to take a few days to get everything written up for all the different ROMs.

Instructions have been updated to include Evo 8 9417008 and 94170014 ROMs. If you don't see your ROM in the list of ROMs (this is a USDM-only mod), please email it to me, and I will find the tables.
I'm now looking again at the '05 Evo 8 and '06 Evo 9 ROMs to see if I can find some additional tables. I may be posting up a few more tables for those ROMs in a few days.

If anyone is interested in one, you can take my spot. I just recently was sent to Texas for work, and the EVO went in storage for 12 weeks, so I won't be using if for awhile.
Mrfred, if nobody pick up my spot, let me know, and I will pick it up anyways. No sense in me picking it up if I am not going to be able to get to the car for 13 weeks at the current time. I will be in for one down the road. Like I said, if nobody picks it up, let me know, and I wil get it anyhow since I was committed.

Yeah, I have an electronic autometer cobalt gauge. I bought it about 2 years ago and it was the best gauge they sold at the time (for accuracy). It re-calibrates itself at engine startup.
My point is here that my gauge reads 25 psi but EVOScan reads 23 psi. I feel that the ECU 23 psi is correct.
Anyone else run into this with a "supposedly" good quality gauge.

P.S. - Defi gauges / Defi link system is in my garage waiting install. We will see how that reads compared to the ECU.
