not to hijack, but MalibuJack could you check your pm's? Thanks

 

Well, if this ends up allowing us to run a MAP sensor as a replacement for the MAF in the near future, then I don't see why we couldn't convert our cars over to a JDM rom since the only real big difference is the MAP sensor. Surely the other items, such as AYC, can be deactivated or just nonfunctional.

 

I don't know why the replacement for MAF keeps coming up.. It offers NO REPLACEMENT for the MAF.. It just allows you to log boost. The adjustments for the MAP sensor are only to stop the CEL light from coming on because the range of the sensor is different than the MDP sensor, and because the range is different, it may throw an error until we can adjust it.

Some day, somewhere, some point, in the future, someone might write code to do that..

But The sensor is NOT a replacement for the MAF.. the JDM rom is not a Speed density system.. Their all basically the same.. the difference is the MDP sensor doesn't read boost, the JDM sensor does.. It has nothing to do with MAF.

 

I'm looking forward to the day someone writes a code to use the MAP sensor as feedback for the factory boost control system. Closed loop boost control through the ECU sounds pretty kick ***!

 

I'm certain that boost reference closed loop control will eventually be developed, I'd even guess that using alternative MAF or even speed density conversions will be possible..

But at the moment, the only thing the MDP sensor is used for (according to several earlier posts and the Evo service manual) is the EGR system (its used to measure the pressure differential when the EGR is open and closed) By switching to the MAP sensor you alter the range of the sensor, and therefore the output it sends. Its compatible with the ECU and its programming, but we have to find the calibration table for it, because its likely the sensor will cause an error with the EGR system (CEL light and probably the mode 6 EGR test result would fail)

Ahh, all these things to look forward to!

 

Sorry my bad for saying the same thing twice. I'm just so excited thinking thinking about the future possibilities!

You know you rock right, MalibuJack?

 

Thanks For this ADD me in+1 for MR. SNOW also thanks Jack

Thought I would have my car back together this past weekend so I could try the sensor, but a few pieces I was waiting for didn't arrive. Gonna get it back together over T-day weekend.

 

one for me please.

 

And Evoscan already has support to log/display boost with this?

 

yes. MDP I think.

When I used to log with my pocketlogger I was able to log the stock 1 bar MAP sensor. IIRC, it maxed out @ 17.6 psi. Can Evoscan do the same thing? If so, then count me in. I would love to be able to log boost via Evoscan.
