For launch maps why not use VSS instead of TPS so you dont have to ease into it. For heads up racing this might be the difference between a win or lose.
Anyone know what page the latest version of the 88590015 is on, i'd like to test it out?
Thanks

Tephra... wink wink... J/P I know theres a whole lot to check, double check, and make sure everythinhg is stable before its released. Looking forward to it!

"v7t6", as they have been calling it, is basically the 6th alpha pre-release test version (hence the t6) of version 7 (hence the v7).
And yes, apparently the official version of V7 is supposed to be out sometime soon. But apparently David has a real life outside of evolutionm.net too? Who knew? ;-)

*UNTESTED*
I did some work on the MAP sensor I bought, a 3.5 bar unit made by SSI Technologies. It is 0-50psia and works from 0.5-4.5 VDC.
The EvoScan formula is:
The ecuflash scaling that you need to add to your xml (to the top of the TephraMOD xml):
Like I said this is untested but the math works out.
I am using SSI Technologies part # : P51-50-A-B-I36-4.5V-R which you can find at digikey for $70 or so. It is rated for automotive use and is accurate to within 1% of full scale (half a psi on this application). Digikey doesn't't offer it but they offer them with packard 3 pin connectors, 50, 65, 75, and 100psi (and more) flavors, just call the manufacturer.

I'm trying to log my Zeitronix 3.5 bar MAP sensor through EvoScan and I'm having no luck getting a formula that works and produces results that match what I get through my Zeitronix datalogger (which matches my EBC display). I tried what you have above and it didn't work for me, nor am I getting anywhere on trying to derive a linear formula. Is anyone successfully logging a AEM/Zeitronix/Kavlico 3.5 or 5 bar MAP sensor on EvoScan?
Thanks.
Thanks.
Aem doesn't use Kavlico.
Anyhow, I was under the impression that evoscan has been working with the zt2 map sensor for a year or two now.

ok guys...
any last minute changes to V7?
- keep or drop the "100% duty under load" ?
- fix or leave the 0ms timer for ADC0F bug?
- scrap MAP averaging or leave it (given some SD funkyiness which may/maynot be cased by it)
*hopefully* I will have time to do 88590015 tommorow, so these last changes can be rolled into it at the same time
