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

I believe the current latest version is v7t6, but I can't seem to find the link to the v7t6 version of 88590015 to point you to.

I believe the latest version for the 88590015 is v.6, before he found some code changes (that I do NOT understand) that turned into v.7... You can DL the v.6 version for this rom, as its stable (Im running it) on the first page. Im hoping the Final version for the v.7 will coming out very soon. 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? ;-)

It looks like you have too much correction. Did you modify the correction levels at all? You want things to look more smooth than that.

I personally think V6t is significantly better than v5.10 since it has gear based boost. Other than that v7 will have launch maps and a few other features.

Thanks Fostytou, never touched the boost error correction table. I will check it out.

PHP Code:
<DataListItem DataLog="N" Color="" Display="SSI 3 BAR MAP" LogReference="SSI 3 BAR MAP" RequestID="38" Eval="0.248795*x-20.9687" Unit="psi" MetricEval="" MetricUnit="" ResponseBytes="1" GaugeMin="-14.5" GaugeMax="40" ChartMin="-14.5" ChartMax="40" ScalingFactor="1" Notes="" Priority="1" Visible="False" />
The ecuflash scaling that you need to add to your xml (to the top of the TephraMOD xml):

PHP Code:
<scaling name="SSI 0-50psia MAP" units="psi" toexpr="(0.248795*x)-20.9687" frexpr="(4.019373*x)+84.2810" format="%.1f" min="-14.5" max="36.254" inc="1" storagetype="uint8" endian="big"/>
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.

Zeitronix is a more precise sensor made by Kavlico.

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.

Found the problem. The Zeitronix software applies a different formula to the raw signal when it goes into vacuum (divides by .491154 to convert to inHG). Once I figured that out the numbers are much closer.

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

I vote to KEEP the 100% duty under load, I love the snappiness it gives the car under daily driving conditions. If you set it up properly it works great! The other two I never had issues with so I cannot speak to those....l
