Waiting on my MS and want to order anything else I need today. Contemplating Knocksense, definitely buying the GM AIT for MAF removal and WANT to install the GM CLT as well but can't seem to find a good place / adapter to install. I really like Joe Perez' adapter but I can't exactly run out and buy one of those! Seems like most folks are using EasyTerm, I'd just prefer not to. Any good solutions?
My car is a 95, 1.8 w/ M45 S/C (hotside) - turbo to come next summer ....once I figure out all this MS stuff!
What do you guys think about tapping the dummy TB to mount the AIT until I go turbo?

the resistance value is know.
the only issue is when piggybacked, because you add bias resistors to the circuit. You can remove these, however, the stock bias is somewhat unknown. For a 90-93 I have them spot on. Since I don't have a 94-97 I cant tell you values that work the best. Seems like paul and others don't have issues.

That's just it, I AM going piggyback to keep A/C. Anybody have the values spot on for 94-95? How does one go about calibrating / figuring resistor values?

Even Joe Perez isn't using Joe Perez's adapter anymore. I built that thing for a dash gauge that turned out to be a POS, so I just linearized my stock gauge instead. It's still sitting there in the heater line, but it's not connected to anything.
I'm using the DIYAutotune PNP values for my standalone MS on the stock sensor. They seem to be accurate to within no more than +/- 10°F across the board (or at least down to 50°F anyway) and I'm quite happy with that. For the standalone 1.6 using the standard bias values, the numbers are:
; °F , Resistance
; -4, 16150
; 104, 1150
; 176, 330
For the 94-95, they show the following, which I'd guess is also damn near spot-on:
; °F, Resistance
; -4, 16150
; 104, 1150
; 176, 320

I'm been ******* with the piggy backed stock CLT for nearly a year and the bastard has never really worked right with the MS. It's spot one from 14*-55* then it get's stupid. I've tried all sorts of values and nothing seems to work. I ordered a CLT from trail tech and one of my vendors is making the M12 to M6 adapter so I can screw it into the water port next to my turbo oil feed line. Once I have it tested out I may offer these adapters to those interested in simplifying their parallel install.

my values are spot on....CLT and MAT read within 5°F of each other in the mornings.
Keep the resistance scale as a constant, and change the bias. you dont need to reflash, just overwrite teh .inc files. open MT and see what the temps display. you shoudl be able to dial them in and have a value that others would surely appreciate. do this while the ait is hanging out in the open and have a thermometer near it to verify the temps...then adjust the CLT bias to get close to the AIT reading.

Obviously it's possible for it to be accurate at on temperature and screwed up at another, but the fact that it typically reads in the range of 190°-200°F when fully warmed up jives with what I know the actual "normal" operating temperature of my engine to be, so I assume it to be accurate at that range as well.

Here it is for the 1.6: https://www.miataturbo.net/forum/sho...7&postcount=13
And here it is for the NB: https://www.miataturbo.net/forum/sho...0&postcount=21
The 1.8 NA is about the same as the NB. Different pins, same concept.

Thanks Joe-
I'm not sure of a couple things though...
what's the A/C Amplifier? What is meant by 'gate it'? How / why would you use transistors instead of relays?
This may be a little beyond me technically and a LOT beyond my motivation to build/sort!
I don't think it'd be any harder than the NA A/C. If you've got a '99-'00 diagram in front of you, take the LG/B wire coming from the pressure switch after the "A/C Amplifier" that goes to 1P, gate it with an output that goes true when TPS = WOT, and use it to control either a DPST relay or a pair of open-collector NPNs that ground the "A/C Relay" (L/B wire at 1S) and the "Condenser Fan Relay" (L/W wire at 1I). I freely release that concept to the public domain for all uses commercial or non-commercial.
Can you help me out a little though? I'm not a complete electronics idiot. I've built circuits in the past and took electronic applications and theory courses in high school and early in college....but that's been a while!I'm not sure of a couple things though...
