1.6 auto throttle body w/ TPS
Like the title says. A complete throttle body assembly out of a 1.6 automatic car, with IAC and a working TPS. The TPS on this unit was shot when I bought it. I wound up converting my old TB to accept a Honda TPS, so this one is for sale with a recently acquired working TPS attached. Also includes the 4-pin TPS connector you'll need to hook it up.
$70 will basically cover my cost on this, so that's the ask.

The TPS itself is not PNP with a manual 1.6 throttle body- auto and manual 1.6 Miatas actually had a different throttle body. However the complete assembly will bolt right on to your intake manifold.
It uses a different connector than the 1.6 manual TPS (4 pin vs. 3 pin) however I have the mating 4 pin connector which you can splice into your wiring harness.

By eManage, do your mean EMB or EMU? If EMU then I'd suggest modifying the wiring harness to take advantage of the A/T TB. You'll need to grab +5Vref from the AFM and discard the WOT wire.

well i have a stock manual ecu with emb (that i havnt set up yet) with a t25 turbo spearco front mount intercooler rising rate fuel pressure regulator a walbro 255 pump and soon to have 460cc injectors.
i do have a torsen, act stage three clutch and fadanza fly wheel if that matters!!
not to pick your brain but do you think my 300whp goal is to much for this setup?

Well, if you're lucky you might be able to get it to idle.
Seriously. A Walbro 255 and 460cc injectors, with an EMB?
Ok, so no first-hand experience on the Walbro, but a lot of folks have reported that the 255 flows more fuel than the factory FPR can effectively bypass, causing a pressure rise on the fual rail which translates to too much fuel when not in boost.
The one I do have first-hand experience with is trying to run huge injectors with an EMB. (Well, I emulated it with my EMU for kicks one day.) The EMB just doesn't have enough range to work with on the AFM signal to control those suckers at the lower-end of the load chart.
You've got two avenues that I can see to salvage the system:
1: Ditch the 255 and replace it with a 195HP. Sell or trade the 460's for some 300-330cc injectors.
2: Ditch the 255 and go back to the stock fuel pump. Sell the EMB and the AFPR and buy either a megasquirt or an EMU.
