TPS load tuning MAP location

Postby trentreznor321 » Tue Jun 28, 2016 2:28 am

I plan on changing from a Microtech to an Elite 2500 on my R33 RB26, and was thinking of changing from MAP based tuning to TPS based with MAP correction. In this configuration, where is the MAP sensor placement suppose to be? Before or after the ITB? Normally for MAP based it would be after the ITB, but does that change with TPS based with MAP correction?

On my jet ski, (ITB/turbo), I got my MAP signal from the plenum, before the ITBs. It was a little strange to tune, but not bad once I got a handle on what was going on. That is the only engine I have experience with ITB/Turbo, and tuning was a little more difficult since I had to ride around with my laptop in my backpack.

It needs to go where you see vacuum and boost. Typically there are ports on each end of the vacuum chamber, but simply connecting in to the same hose going to the fuel pressure reg is fine.
