This next post is just copied from TBSSOwners - but basically to sum it up we had DSX Tuning in St. Louis build this custom MAP sensor.
I just wanted to throw this out there to share. We're wrapping up my 416/jack shaft 2300 build now and we had run into some problems with the MAP sensor. I wanted to tune SD for a few reasons and we hard built the intake without a MAF port.
As we neared wrapping up the build we realized that the position of the sensor port on the LC32 made mounting a MAP sensor a bit tricky, especially on a build where we would be relying solely on the MAP signal and fitment/seal would be critical.
My original plan was to run a LS2 style sensor I had bought from Dave at DSX Tuning months ago. I hadn't really bothered to check fitment as it wasn't on the top of my list. I made a small bracket to hold the LS2 style sensor in the port but wasn't happy with it and soon noticed that the port size was actually bigger.
Anyway, I contacted Dave and told him what I needed, essentially a mirrored image of an LS9 sensor so the wiring harness/connector faced away from the cog drive instead of into it.
The space is super tight so using my artistic abilities I traced the port/mounting area and took some measurements for Dave.
Center bore/center bore, diameter, bolt size etc we're all sent to Dave.
A few days later he sends me these photos:
And after another couple of days it showed up at my doorstep!!
I was a bit nervous of my measurements, but as it turned out they were spot on.
Dave's craftsmanship is second to none, this sensor look and fits exactly like you'd expect an OEM sensor to. I should also point out that Dave informed me that the LS9 sensor would not work for me either as the 06 ECU will only support 2.5bar, and does not allow for negative scaling. This certainly would have been another headache for me as I did not know this.
Thanks a ton for the help Dave!
