Street Build ITFLYS - 1Gina2G

[Stapl3]

Check out MPXH6300AC6T1 (3 bar) and MPXH6400AC6T1 (4 bar). These work and are tiny. So, maybe anything more is designed larger to look important or stand out as a mod?

edit agreed above, AEM stainless is what I would go to as well. I think 3 bar would be ideal for him, not 5. Resolution loss for no reason.

Slow down now - I upgraded to the AEM 3.5 bar for Speed Density back in December: Link

There was a whole thing about signal noise at high rpm and such.

This GM sensor came with the Autometer boost gauge, so I left it connected, just for the gauge.
At this point, I’d settle for a “working” sensor for the gauge - it need not be to the same precision as what the ECU is using.

Hmm, anyone know what voltage is driven by the ECU to move the stock needle on the factory cluster? I could run the ecu output signal to the boost gauge sensor input, but I don’t think I can calibrate it.

MAP Sensor - GM 3 Bar MAP Sensor

GM 3 bar MAP Sensor - assembled in the USA, compatible with MS3Pro and all flavors of the MegaSquirt EMS / MicroSquirt EMS.

Maybe try that one? It talks about the cheap chinese made Delphi units coming apart on people, and that theirs apparently don't have that problem?

What worries me is the Omnipower sticker on the stock-photo they used. If it's just an omnipower 3 bar map sensor then that needs to be stated in the ad instead of it being called a GM sensor.


Edit: Also found this on eBay. Ad states Genuine GM made in USA so maybe this ones better?

This enables the air mass to be precisely defined. The pressure sensor case can also incorporate an integral temperature sensor, whose signals can be evaluated independently. This sensor has a better than 1% accuracy from -40 to +105 degrees-C, with a capability (margin) of 1%.

So freaking clean.

 

[MindBlowin03]

The GM style sensors are just terrible quality now, drop the coin on an AEM stainless 5 bar map sensor and never have another issue.

Agreed. The GM sensors used to be the go-to and now they are just junk. I switched to AEM a few years back myself.

So freaking clean.

Thank you - really. I find keeping a clean setup makes diagnosing issues easier. As soon as I see grease, oil, dirt whatever collecting - finding and ending the issue saves me from catastrophic failures and general unhappiness.

Is it ego? (uh yeah) - Is it homage? (definitely). I'm trying to build a version of the 2G Eclipse that Mitsubishi could have built as a factory prototype - An amalgamation of the best stock parts and minimalist modifications pushing out the specs of the original factory engine and chassis to achieve unexpected levels of performance.

Where can I get a new harness plug for the coolant sensor?

This one or a different one?

Reporting to you now from a remote corner of Canada, where the power is out, but the TV, SAT, Internet and phone are still on - thanks to the amazing power of "burning gas" in the generator. Lord, the sooner I can get this place on a all house battery, the better!

 

[CrackedDSM]

are you doing in Canada, eh? What's that all aboot?

Seems like everything I need to finish the head swap is in shipping. The biggest time suck will be replacing connectors on the wiring harness. The crimping, shrinking, and covering is something I like to take a bunch of time with so that I don't have to go back to it later. If it looks like it was done at the factory - then the smog guys just sort of glaze over and push it through.
