Could someone help me with adding merpmods to my current map and shoot me the definitions? I have used sharptune to convert my map but I haven't exactly succeeded. HEW is in limbo for me because my registration doesn't seem to be getting through. It's AE5L500V and attached in the zip.



13 downloads of this map like its gunna be a free tune for people? I am not a tuner so i don't suggest anyone uses this map but me.... Unless one of you 13 have converted it for me and know my tables are fine?

Do you have a revision for A2UJ000J? I looked at the rom for the 06 sti, but it seemed to be incomplete. Please let me know what you have for the 07 sti.

I've got a 2010 USDM sti. Im assuming AZ1G202I-Flex2 is the right rom for my car. When I try to open it in ECU flash after pointing it to the definitions in the zip, it doesn't load any tables.
Im able to load AZ1G202G_FLEX-5 just fine from what I can tell.

I have ported this rom to other years no issue except trying to go 2015 and newer, it will flash and run but the CAN is different. I have had cel wont turn off issues before on 2015 and later with rear o2 and egr DTC not defined

If you have evap and SAI deletes, it's highly likely you have the same code i have. It doesn't show in btssm or through the tactrix related programs but I CAN pull the code up with a cheap cr123 scanner, and other generic ones....

P04AC is my specific one, and it is a ghost code because I disabled the codes on the tune for the delete but the youtubers are all wrong about it not through codes... Ultimately if you have the purge valve you deleted, that's closest to the pwr steering, and just plug it in (still deleted) the same way you would have for the barometric sensor, the code will stop throwing a cel.

This goes for other evap related delete ghost codes, and i have seen a few struggle with TGV, so instead of tucking, deleting or repurposing the harness plugs.. Add back one sensor at a time and re test a few start cycles. The code will clear and disappear obviously each flash and clear cycle but it returns on startup as "purge valve stuck open"... It's literally just a couple pins that can be shorted i think if your determined to find that out.

I have seen one instance specifically were the ae5 map was swapped onto another year that this worked.. for me my car is a 2013 sti sedan so that is my map.. but I'm certain the map tells the ecu to check for the evap stuff regardless the code is off

LATEST BUILDS ATTACHED TO THIS POST

so you can use AE5IB00V MerpMod patched rom below on any AE5 rom in theory :)



STI
Market: USDM
Year: 16
ECU ID: A62A907107
Internal ID: AE5T201V

- Copied that ff9-ffd part from mine to AE5IB00V-patched, everuthing else is same up to 2000 slot.
- flashed that one in, car tried to start for like 3-4 sec, started, revved for a sec and wend down again, revs were not shown on the dash, I guess it won't work to just copy-paste from any other AE5 rom, has to be AE5T2***, right?
- flashed back to stock, car starts right away, works normal, dash shows revs.

Can someone help with getting AE5T201V patched?

Thanks!
Took me some time to find it, reposting again so folks can find ae5r100v patched.
Will report back if works, a bit sad it does not have flex though...

**UPDATE**
Memory up to 2000 was identical so no changes needed
Runs good, but still makes me a bit sad not having Flex capability
