Fixing A/F ratio

[pittster]

Its not a big bang for your buck, but why not, it improved my mid by a few HP but the torque was extra nice for riding the Adelaide Hills which are tight and dirty.

Best bang for buck is front sprocket change.

Main purpose of a Power Commander (contradictive to its name) is not HP or Tq increase (although this will happen), its to improve AFR through every throttle position and rev range to suit the mods you have done to your bike. Biggest benefit is improvement to throttle feel and bike feel. Also remember most people just put a map in they got off the net which will only give about 60% of the true potential from a Tuning center tuned map.

Have you had a full service including the air filter and plugs changed and the valve clerences checked? I've been told these can be iffy with a dirty air cleaner.

Other than that, flush oil, check oil pump is getting pressure to the top of the motor and change the coolant.

Hasnt had a major one yet. Think ill book it in for one first then get the AFR checked.
Oil, plugs and coolant have all been done.

So any of our sponsors sell a PC3 cheap?

If it needs the valve clearence done this can make it run hot. As the shims wear the valves don't open as far, not letting all the exhaust gas out, building up heat in the cylinders.

What's the evidence of this? I can imagine you'd have small differences here and there to varying degrees no doubt, but surely sometimes the dynojet map is spot on for that engine and you could spend hours looking for tiny gains!?

The vendor i brought it off claimed i could expect between 0 to 3 more hp from custom mapping.

The full akra pc3 map for my bike from the dynojet site tested a very good consistent a/f ratio on the dyno. Was tested on the same day with Disco's 6 and the curves and figures are impressive, lastly the bum dyno says it's all made a huge difference through the rev range.

I'd be extremely surprised if I'd only got 60% of what's possible with the supplied map. Just saying because people need not think they necessarily have to get custom mapping for their system if there's a good match for them from dynojet/ other bikes.

Ps, sorry for the hijack, I hope you sort out the heating issue Owen, I've got nothing...... Maybe it's in menopause

Wasabis bike just needs a ride to wattieland to clear the carbon build up
From commuting.

if you no how to use a PC a data loger is your best bet for tuning+it shows the actual tune in the real world and thats on the track or road but if you can go the PCV it has a built data loger +repairer as for the heat side coolant only is there to stop coroshion and freize point + boiling point if you have to much coolant in the motor it will actuley run hoter as its much more dence than water.you have to have a good ratio(water to coolant) to get the best out of your cooling system
