Re: TPS range too small

An electronic solution which involves analog stuff is possible.

Use a simple opamp in noninverting mode and run it off of the 5 V supply in the MS

Put in a couple of resistors to get the gain right and another resistor to get the amplifier output close to
0,2 V at closed throttle. This way you ...

Re: TPS range too small

You're talking about the Alpha-N TPS map, not the TPS itself. I've been playing with this recently.

Yes you can set the table up so that at low RPM you have more resolution at small throttle openings.

I set mine so that the first 10% of throttle gives "60 kPa". With my VE table set linlearly from ...

Re: TPS range too small

I'm guessing you're talking about an MSII installation right as in MSI you just put the raw values of TPS on the Y axis of the table...

My concern is that I can't get the resolution I'd like at low openings as a small change low down makes a big difference and the MS won't be seeing it... For ...

TPS range too small

My TPS only gives me a range of around 130 I have adjusted it to give me different readings at closed throttle but I still only get a range of 56-186 which isn't great for tuning low throttle openings in Alpha-N mode. I'm GSXR TB's so the first few degrees of opening change the flow dramatically. My ...
