Guys:
heard a rumour that the ix has a map sensor as standard and not a maf sensor as on previous evo.

now, can you guys

a) confirm or dismiss this
b) advise if ecutek will be usable on the ix ecu if either sensor is used.

plus any experience yet of mapping a ix? or any thoughts on the subject would be appreciated as will be coming to you for a map session in a month or two when i get my car (should be 3 weeks now) and bits bolted onto it.

cheers

Im not WRC but i know the GT IX i looked at today had a MAP sensor, no MAF :coolsm:

 

[sean_goodman]

and i understood that ecutek would not work with map sensors, does this mean that the only mapping option for the ix is the new ecu route??

whilst i was concidering a new ecu for my ix i was more than likely gonna go the ecutek route as i will be stopping at exhaust and filter anyway

anybody know more bout ecutek?

anybody know more bout ecutek?

would suggest that you send an e-mail & ask the question to here:

this is not a WRC contact...it's EcuTek direct

Hi All,

All of the above is correct

The EVO IX runs MAP, Inlet Temp, and MAF. ECUTEK programming is no problem, and Mervyn has had a detailed look at a couple of cars already.

Interesting point - the Monaros that we tune run a MAF, along with a temp sensor and MAP sensor.

We can turn the maf off - and tune as a mafless setup through our programming software. There are around 270 individual maps for the ecu progarmming - so it gets a bit complex. But the ecu continuosly performs calibration checks on the MAF - and if results are returned outside the acceptable limits the MAF is turned off and reverted to Mafless setup. The MAF tune is usually a much more accurate way of determining engine load and fuel requirements than MAFless.

The car still runs exactly the same - but the diagnostic system registers the fault immediatley. The change with the EVO 9 could simply be an application of the same principles - as MAF sensors do fail or go out of range occasionally - and Mitsubishi may simply employ this system as a form of 'engine insurance' if you like.

We had two completely standard Subaru WR1 cars on a dyno day recently with MAF sensor that were out of range. These cars made more power than the other standard WR1s, but the MAF scaling problem was telling the ecu there was less airflow/load than was the case. Consequently the ecu delivered less fuel and more timing - more power came as a result, but as the problem gets worse it is only a matter of time before it becomes a serious problem.

If you simply remove the MAF and tune Mafless - you get CEL problems immediately on the Monaros. Similar programming options will probably be available in future versions of ECUTEK, but for now we stick with MAF tuning.

I hope this makes sense.
