can evoscan log boost on a jdm car that came factory with a 3 bar map sensor? if so is anyone aware how to do it or what calculations evoscan needs to do it, ive tried just ticking "boost" and "jdm map" but its seams wildly inaccurate. as per usual any help is appreciated

Hi,

What rom is in your car?

Mine is 98640014 and I use this formula, it gives an approximate of the value.

(2byte Load - Baro) * 0.145


I don't remember the thread where i read that, while trying to find the info
on how to log the jdmmap sensor that our cars have (without success )

Hopefully someone more experienced may chime in.

Best regards,

hmm i noticed some VIIs came with a MAP sensor.

if your using the above equation u have to make sure u actually log 2byte Load.

yes i am logging 2 byte load, so what would be the exact code i need to enter into evoscan to do this, do i have to set a "custom" item to log and then enter a code?

u can make a custom or change the original JDM MAP. up to you really. let me know how it worked out please.

so what would i need to change in this section of evoscans xml to get it to work

<DataListItem DataLog="Y" Color="" Display="JDM MAP" LogReference="JDMMAP" RequestID="38" Eval="0.19347*x-14.51025" Unit="psig" MetricEval="" MetricUnit="" ResponseBytes="1" GaugeMin="-15" GaugeMax="30" ChartMin="-15" ChartMax="30" ScalingFactor="1" Notes=""/>

go into evoscan itself and you can alter the formulae, i dont know how to do it like this by referencing 2byte
