I would also like to put in a request for the 9653 rom, it is the easiest (most problem free) rom for those of us using evo8 ecus in 2g DSMs to use and I would love to try this out.

I haven't heard a price yet. With enough of us, it should be easy to cover if we split it.

I would be willing to contribute to this also.

Edit: What happens when you try 94170015 on a usdm 05?

I just Pm'd him. Once I hear back I'll PM all those interested so we can spark his interest back into porting this for the 9653006 ROM with some sort of bribery

Is there any good reason not to use the patched rom? I certainly have fewer tables in my rom that have been altered than in the patched rom. Is there something done to this rom then that would mean that I can't just copy to it instead of the other way around (just like the install for a Tephra rom?). Specifically referring to 9055 if it matters at all.
It looks like it can be done either way

Also I just wanted to double check a few other things quickly.

Is there a preference for where the MAT sensor output goes? I've seen some discussion saying that it is better to leave the AIT sensor locked and run the MAT through the fuel temp input but which does the 9055 rom assume we are using? Probably the AIT input but I wanted to be sure.
it appears that it goes in the IAT slot if you are just using the SD patches or it can go in the fuel temp input if you are USDM using the MAT patch. More instruction here

This sounds counter-intuitive to the table name, but that's because I didn't do such a good job of naming that table.

Do I need to adjust the scaling in ecuflash for my GM map or do I just adjust VE to compensate?
The way I understand it we change the scaling using this
<scaling name="MAP 16bit" units="kPa" toexpr="x*100/82" frexpr="x*82/100" format="%.0f" min="0" max="400" inc="1" storagetype="uint16" endian="big"/>
Copy the MAP 16bit table from ecuflash then change the function in your xml. Fire up ecuflash again and the top row for this table should have changed but the bottom row will be the same. Return the top row to its previous values (before the change in the function) and alter the last cells (top and bottom) to the highest that the sensor can show (311 I believe for a GM map). I was making this part much harder in my mind than it actually is.

I'll start rereading the first success thread tomorrow to see if I can answer my own questions.

There is no option to use the fuel temp input with the 90550001 (non-USDM) ROM. You'll have to use the IAT sensor input.

I think the GM MAP scaling is somewhere in the thread. I'll find it and put it in the first post in a day or so.

I posted it in the other SD success thread, but what version of the knocklight is the 94170015 using?

Hi mrfred!

I am about to give this a try and wanted to clarify something on the IAT. The SD patch will look for the IAT in the Fuel Temp pin as your original post for installing the IAT. Am I right on that assumption?

Also, on the USDM Evo 9 rom, the "SD set baro value", the value comes at "0". Is that right? (See attached pic).


Thanks in advanced!

Hi joedr. There are two options for reading MAT. One option is to use the fuel temperature ADC input. If you want to use this method, then you'll need to install the "MAT logging patch", and then the "SD Conver IAT to MAT (0x03 -> 0x0E)" entry needs to be set to 0x0E. If you want to use the IAT signal wire, then no need to install the MAT logging patch, and leave the "SD Convert IAT to MAT (0x03 -> 0x0E)" entry alone (keep it at 0x03). I know that last step sounds counterintuitive, but that's because I picked a lousy name for the table. I will be updating this table name in the future.

I've finished porting SD to the 96530006 ROM. I'd like to have someone test it before I post it. Does anyone already have a MAT sensor installed that can test it this week?

Nice job mrfred

ARGH. I didn't get my sensor installed this past weekend (too busy fighting with the wife's scooby), and I won't have the time to do any physical work on my Evo for at least two weeks; otherwise, I'd jump on it.

l2r99gst?

My penance for not being able to help with this will be to work on rolling a patched version of 96530706 with DMA logging, since I've been missing that quite a bit since switching to tephra's latest version.

Thank you sooo much mrfred! my motor is doa right now- but as soon as i get it back up and running I will be using this patch
