FWIW, I'm using the identical-looking-but-sold-by-diyautotune-for-a-lot-more-money GM 3 bar sensor on my car, it's been working great. I've had it since June or so.

I have it wired to EXTMAP, no special conditioning, although I did need to add a +5 output to the db37 on my mslabs ms3.

Is it a "GM Style" or is it an actual GM sensor.

When you're scoping the abs sensors for me could you do a basic voltage test. 0psi, vacuum, and then boost? If our suction is calibrated correctly I can tell if the sensor is good.

I need 5v out for the oil/fuel pressure anyways, might as well get a line run to the engine bay.

It's the one DIY auto tune sells. I think it's genuine GM, but I dunno, there are a lot of counterfeits out there.

MAP - GM style 3 Bar MAP Sensor DIYAutoTune.com

This is the calibration I use:



TK derived the custom calibration by hooking up all four sensors (builtin, GM, plus a couple of the mouser ones I bought for measuring back pressure) to the same line, data logging at various MAP values (mityvac is useful for this), and then massaging the data so that they line up. I don't know what the curve-fitting algorithm he used was.

GM is 0v->1.1 5V->315.5

So close.

Nominally. They vary a bit. That's the calibration that DIY auto tune says to use on their site, but the custom one works better for my sensor.

Star Spec ZII or 595rsr.

I'm leaning toward the rsr because its a $150 cheaper. But at the same time I really liked the z1 star specs when I had them.

I'm hung up.

I know turbofan will say 595RS-R and curly will say z2's.

Will the z2's last 32% longer than the 595s?

I dislike the RS3 availability. I will get some of those when I get 15x9s.

I only see rival s in 15". I thought those wore like crazy.

Are you looking for 14s? Yes they wear quick, we got maybe a season out of ours. The xs lasted almost 2.5 seasons with a shitty alignment and were only a second slower on a 1:15 course.

I was talking about the non S, I have 0 experience with the S.

What size tire are you looking for?

I think the forum consensus is the 595 in any case.

Maybe with the release of the S, they discontinued the non S in track fitments?

I think this is the case. It's the "S", or nothing.

FWIW - I have a set of "gently-used" 225/45-15 Rival's (non-S) on 15x8 Konig's that I'll let go for a song (to finance some 15x9's next year). They were only used on the street

PM me. But probably not, unless they are the same price as new tires.

I positively despise the second one. The first one is super ricey but also kinda cool in a way, how it turns down.
