Hi All,

Yup, I am the Honda VFR 800 fuel pump champion - and it is still working delivering into the original Honda VFR 800 pressure regulator (3 bar) and running dry - i.e. not submerged in fuel. It runs nice and cool and powers my non-stretched application very happily (my maximum fuel ...

:RTFM: Hi,

If you are still having the RF problem, I think that you will find somewhere that the VR sensors cable is reversed polarity on the V1 Microsquirts (i eventually found the reference after I had sorted out the problem!). I found it out the hard way!!!! interference and resets everywhere ...

Hi,

Well to try and answer that question. Firstly, yup you need a very rich mixture to first fire a 2-stroke, I have heard the figure of 6:1! Basically because you need to wet out the crankcases.

Currently my engine starts as follows: -

key in ignition,
turn engine over - electric at about 600 ...

Not sure if you have had a reply to this or not, but do please look at the post further up about AlphaN on a two stroke. Ian's suggestions were very helpful. You DO need to set the 6x6 map for throttle position into a linear ramp as per Ian's suggestions - you also need to change the Alpha/N v.s ...

Ian, 8) :yeah!:

Sorry, it has been a long time since I replied and gave you an up-date. However, during that time I have been VERY busy, I replaced all of the ignition and put on modern Honda coils (4ms dwell with a 0.9mm plug gap), changed onto a phonic wheel on the fan of the dynastart, blew up ...

Ian,

:)

Thank you so much, I am now starting to understand how to get Alpha-N to work. I have re-set the Alpha-N TPS table as you suggest, And think that I am now on the curve of getting the Cranking and Warm up ramps into place, Tickover was sorted out yesterday. Pity that the uS and MS2 ...

Ian, :) :?

Many Thanks, a great pity that pure Aplha-N on the Microsquirt is only a 6x6 table, it could make it a bit difficult to get right on 2-strokes with pulse tuned inlets and exhausts where the torque curves can be highly non-linear! (and YUP I have both a megaphone inlet and tuned exhaust ...

Hi, :RTFM: :? :!:

A bit off the wall this one, I am trying to fit fuel injection on a 2-stroke twin of 400cc (1958 vintage). I have a set up with a Microsquirt ( running 2.88 code), 36mm throttle body with TPS and MAP and a single 3bar injector (220cc) (Honda VFR800 pump delivering 7gph @ 3bar and ...
