Re: Susuki TB/Injectors setup for TR6

Staged injections works with MS, and is the technique for bringing injectors in as the revs go above a threshold.

MS2 is better for this as it can bring the second set of injectors in over some engine cycles. MS1 doesn't have the power to do this.

Re: Logarithmic TPS any experiences?

Thanks David for your thoughts on this.

FWIW:

I discovered a few things:

1) The gsxr600 TPS is not spring loaded, and although it doesn't appear to have any slop, the later TPS that Suzuki used were spring loaded. I have now used one of those.

2) A simple way of making the TPS non-linear (more ...

By "messy" I meant, that the TPS ADC is not really representative of the amount of air going into the engine, and hence I have limited software control at these low throttle openings . Consequently the AFR is not as stable as I would like it to be. It isn't noisy (i.e ...

Re: Logarithmic TPS any experiences?

So, I was looking at the TPS output (using the excellent PalmLog software).

It hangs around at the lowest ADC setting for a long time. I can get the engine up to 3500rpm before it increments (from 58 to 59, maximum is 225). Actually the car works nicely, but I think logarithmic TPS might help my ...

Logarithmic TPS any experiences?

Hi there,

I was wondering whether anyone had any success with logarithmic TPS. It seems to make sense on some installs (I have gsxr600 ITB's on a GSXR1100) and low opening are a bit messy, and AE isn't the best.

Just wondering if anyone had any experience. I found that Webcon can supply these (see ...
