Figures. If anyone has a busted evo maf they want to sell cheap PM me.

 

you can get the same MAF connector from any post 99 galants (except for the 3.5 and 3.8 liter - haven't confirmed it), all versions of the 3g eclipse (except for the GTS - not confirmed yet), the 2g 3KGT NA, mirages w/ the 1.8 liter from 98-02, and the modern lancers via NA or the Evo. All of those models have the small pin connector.

 

Cool Thanks

 

I am still trying to figure out who is the supplier of this particular connector.. its not BERG, AMP, Molex, Its probably DENSO or Mitsubishi Powertrain, unfortunately neither has an easily available parts catalog to match the connector. Too bad its not AMP or Molex, they send me sample parts whenever I need them to test out new ideas.. I just recently found amatch to the Honda motorcycle (Denso) coil on plug connectors, but the Evo/Lancer three pin plugs aren't as easy to find (again I end up salvaging connectors off broken parts)

If your resourceful you can find broken parts for cheap or free to salvage connectors off, its just understanding the interchange... It should be noted that the Turbo lancer guys could also easily swap an Evo. or 3kGT MAF onto their car and get much better results with a piggyback (S-AFC) setup and the turbo kits.

 

I am aware that the GM sensor has a thermesistor, but of all the data and research I've seen, I don't see any GM sensor with a Baro sensor built in. I've looked at the Bosch sensor, Hitachi sensor (also used in the fords), and a few others.. However my point was the Evo ECU has compensations for temp and altitude that really should be used.

This should be useful MAF info..

Also, I've also started doing some additional research on the Splitsecond products, I discovered their ARC-2 Karmann has Tip-in (TPS) compensation that could be useful for the stumble caused by the momentary lag in airflow when opening the throttle.

BTW here's a link for the Pro-M product.. its $514 with a meter and converter.. not a bad price at all.. just remember that the AIT sensor goes into the intake pipe or the car will run terrible with the meter in a blowthrough configuration.

and below it is the "Splitsecond" Karmann kit.. Its more expensive, but it shows some of the components they include.. all you need in reality is the Karmann converter a meter, and an AIT that is calibrated the same as the stock Evo AIT sensor.

 

So what is the best MAF kit to use, and exactly what am I going to need to completely remove the stock MAF sensor.
My understanding is I need 3 parts, the actual sensor, a black box to convert the signal, and an AIT sensor. Do all these come in one kit?
This needs to run on a stock ECU so I can pass emissions testing, but will normally be used with the AEM EMS.

 

Yep, you got it.. the three major components are as you stated, the sensor, black box, and AIT sensor, these components are provided with a complete DSM kit from ProFlow...

This will work fine on a stock ECU, you may need to use the MAF Tuner component if you want to run it with the stock ECU Since you will need to closely match the curve to the stock MAF output. the Proflow kit is close, but still requires a slight retune.

My experience is I have been able to just bolt it up, and run it without having to retune, but a retune is required for best performance. Obviously if you want to run an AEM most of the time, its not critical since that'll be where your tune comes from.

You will need to give the ECU a day or with 2 or 3 run cycles to adjust to the sensor before you take it in for inspection.. and it may take a little time with an OBD-II scanner to adjust the sensor so its adjusted well enough to keep the fuel trims +/- 5% (not throw the ECU into a hunt for an optimum AFR and keep resetting the trims)

Hope this answers what your looking for... My car does pass an inspection with the unit, however it does occasionally through a CEL light due to its tip-in mixture (Sometimes it tips in a bit rich).. so be aware of that while your tuning the car.

 

How do I see the pro flow products? The website link posted earlier in the thread does not work and google has not turned up much.
Also from reading through the thread, the sensor is not in its own separate tube, but rather something that you place inside a standard intercooler pipe via a weld on flange?
Does this mean I can just pick whatever intercooler pipe I like and have it modified for the sensor? Same would go for the intake pipe I get and the AIT sensor in it?

 

http://pro-flow.com/KarmannVortex/opening.html might have been a typo, don't recall..

basically yes.. you have two options, contact them and arrange to have them integrate a sensor into your upper pipe, or buy a blowthrough tube sensor, and cut a section out of the upper pipe and use couplers to hold it in (see my early photos for my prototype that is set up that way.) My new setup has a buschur pipe that they integrated a sensor into.. Contact them for pricing and see which way works best for you.

The intake pipe was cake, I took a multi-bit and drilled a hole the size of a the grommet and put the sensor in the pipe, just remember to look in the pipe when you seat the sensor so the blue "matchhead" portion of the thermocouple is getting air passed it (not obstructed by the plastic carrier) Real easy..

Technically you dont have to run the sensor as a blowthrough, you can set everything up as a drawthrough setup to test everything out (I actually did that for several months before I committed to having the first generation intercooler pipe made up for me)

 

ITs important to tell them what you intend to do with your sensor though, since it will make a difference where the AIT sensor ends up being installed (the drawthrough setup gets the AIT setup in the MAF tube.. You don't want to use that on a blowthrough setup because the car will go into enrichment mode when it sees 100+ degree intake temps.

 

Hey.. Here's a few photos of the new setup from my camera phone.. Haven't had the time to take real pictures.

This is the Buschur intercooler pipe with the ProFlow maf integrated into it. And a picture of my car so dirty you can barely see the paint..

 

Any updates Jack??? Everything working well???? Ime getting ready to install mine, again....RRR

 

I hope you guys can perfect the blow through design and sell them..If we can't get the VPC for out cars then we need something like this..I just like the simplicity of piping and being able to run a intake pipe right from the turbo with a VTA BOV...Is there a real world solution now?

 

Yes you can get the same setup as Malibu from www.pro-flow.com.
Give them a call and tell them you want setup like Jack. I was going to do this, but had to replace my Transfercase. As soon as I get the extra cash I'm going with this setup.
