Not sure but we will definitly need to see if there are changes to be made for those of us using the JDM MAP sensor.

 

I decided to give this rom a shot on my 05 GSR to check the OBDII monitors through the OBD Scan Tech software. It runs fine but will not start without disabling the immobilizer. The only monitors present (as read through the software) are fuel, misfire, component, o2 sensor heater, o2 sensor, and catalyst converter (As labelled in the software). I have a cat and a rear o2 sensor, but I also had tephra's sim mod enabled in the rom. After a short drive all displayed a "ready" for their status. My previous 011 rom also showed fuel evaporative and EGR, both of which are not supported on this rom according to the OBD Scan Tech software.

 

I found a potential issue, either with the rom, or perhaps a bug in tephra v5.

When using NLTS (set to 1500 or 800) at say 4000rpms, there is a blip, revs go up to about 5000, another blip or two, 6000, another blip, and so fourth.

Otherwise driveability is confirmed, I will be testing out mapswitching tonight or tomorrow.

 

Be careful when map switching boost if you are using a three port solenoid. There might be a problem with the patch as the boost went crazy high when I switched maps even though boost settings were the same. Tephra is looking into it but it would be good if someone could confirm my issue.

 

Thanks for testing that. So, it looks like this ROM should be fine for OBD-II emissions testing then, even a little better than the 96940011 ROM, since the fuel evap and EGR are missing from the ROM.

The big one that usually needs to be there is the cat efficiency. It varies by state, but usually for the emissions testing, you can have only one readiness test not ready and that can't be the cat efficiency test.

just quickly for 96530006 2byte load is 0xFFFF8984 - formula should be 0.3125*x in evoscan!

scheides - what do you mean blips in nlts? did you do the nlts test in your garage? ie whilst in neutral - rev to 3000 rpm and press clutch?

 

2byte RPM change too? 3D Table still 36200?

-Jason

 

2byte rpm = 0xffff8962
MUT_TABLE = 0x36200

all of this should be in the 2byte thread

yes if you are running 96530006 then use the 2byte/muts for that ROMID

 

CRAP!!!!!!!

DON'T USE 96530006 UNTIL I FIX AN ISSUE WITH THE ALT-MAPS

Alt boost maps are missing their header information

 

96530006 UPDATE:

I have uploaded a V5.1 - This FIX is only for 96530006, other ROMID's do NOT need to expect a V5.1 for their ROMID.


This highlights the need to proper testing by people, thanks to JohnF hopefully we prevented a potentially bad situation!

Please ppl test your ROM's

 

H O L Y F * C K I N G S H * T!!!! Tephra you are T H E M A N ! ! ! !

I am absolutely blown away. I have been working towards this setup for a while now and cant believe it finally works! I have the map-switching working in harmony with my Aquamist HFS-1 alky injection kit. Alky kit off, low boost pump gas tune, alky kit on, high boost rocket tune! WOOT!

Ok, some notes, to recap:
-you MUST deactivate the immoblizer to use 9653006 in place of the 9694011 rom on the 2005 USDM ecu.
-I raised valet rev limit to 3000 from default of 114, not sure if this helped.
-dropping NLTS Load threshold to 50 alleviated the above issue.
-I disabled all extra tephra mod options I did not plan on using, including auto-valet. Again, not sure if this helps.
-No CEL for EGR delete. I assume this is because there is no EGR on the EUDM cars.
-I am currently using a simple 240k resister from a 12v source to make the ecu see ~5v on pin 42, it works perfectly fine in initial testing, I will be looking more closely at this, possibly switching to the newer version of the circuit others are using.
-I have tested alt maps for different timing, fuel, and boost. All work as you would expect.
-again, tephra is the M A N! Send him money.

 

Glad you figured out how to get 9653006 to work on the 05 Evo 8 scheides. Thanks for doing that as I just didn't have the time the last couple days.

So can I get some comfirmation on some things here?

1. Turning off immobilizer is the only way to make 9653006 work on a 05?
2. Does 9653006 work with a JDM map sensor "out of the box"? Meaning, no table changes need to be made?
3. All alt maps, Fuel / Timing / Boost are 100% working with the switch?
4. Does the GM 3 port work with direct psi-target boost with 9653006?
5. Are the psi-target boost tables able to be used with the alt maps? Has mrfred made XML for psi-target boost for this map?

Thanks again scheides!

 

Hrmm - might ask the mods to close this thread?

Tripple posting is making things a bit confusing!

I guess we can use the new thread for further discussion of using 96530006 over 96940011!
