I'm not sure I am following you. When I switch it to WGduty scaling it goes to 0.0%

 

It reads 5.4 when no throttle, so it's not just a straight offset (since then it would read -4, right?)

 

on mine and many others

no throttle = 12% to 13%
full throttle = 100%

sounds like you need to adjust the sensor

 

You got the right idea. It should read 63%. The problem is that the WGduty scaling assumes the value is uint8, but its uint16. I forgot about that. If you change the address to 0x1e27, then you'll get 62.5%.

 

That worked. Thanks.

 

Are these changeable values? can correction go beyond 16% if changed to a higher value?

 

I haven't tested it yet. I would imagine so.. would need to do some logging.

 

Guys,

I have just added the "ROM Mods for 2004 USDM Evo 8 ROMs 96420007, 96420008" to my 96530006 xml file and all the values have come up correctly.

Is it save to assume that the 96530006 is in the same family of ROMs as: ROM96420007, 96420008? If the "MAP" maps are located in the same spots?

 

Double post

 

Hey Shane,

What are you trying to accomplish?

Does your 8 have a JDM MAP? or any map?

Cheers
D.

 

I can get my hands on a JDM map sensor.
What i really want is the ability to run without an AFM. So looking at the JDM map sensor seems like a good start.

 

ok, but does your car have a factory MAP sensor now? Where are you located?

 

At this stage no it doesn't, but I have 1 in some of the spares i have, it would just be a matter of installing it.

Im located in Australia.

 

You're car doesn't have factory wiring for a MAP sensor, but we've figured out enough to be able to install a MAP sensor on any Evo now and allow the ECU to read and use the data. The install isn't much harder than installing a gauge, but the ECU mods are something that I haven't bothered with yet because I mainly deal with the USDM crowd. tephra is working out boost sensor reading for his ECU though.

 

The wiring isn't really a problem, i can just pinch the loom from a wreak, and connect up the correct pin to the ecu. After that ill try out evoscan and make sure its reading correctly. Ill get the sensor and wiring this weekend, and hopefully fit it up next weekend, depending on how hard it is to drill out the manifold.
