Squeezing More from Bike Engines...
What's the general consensus on getting the most out of your bike engine through mapping?
I'm guessing that the OEM ECU's are slightly compromised due to emission requirements, but given the high-state of tune in these engines,
is there really much more to squeeze out?
If so, does a Power Commander piggy-backing on the OEM ECU do the business, or would a 'standalone' like an Omex or DTA be better still?
I only ask as a 'standalone' can be had for not a great deal more than the cost of an OEM ECU off eBay and a Power Commander unit.
It's Evolution Baby!

Power wise I think there would be nothing in it, but a lot of standalone ecus have other functions built in like flatshift, switchable maps, launch
etc which may make them worth the pennies regardless of similar performance

In my opinion it's essential to have your bike engine mapped to suit the vehicle if you want longevity. The engine breathes completely
differently when its installed in a car and most bike engines tend to run lean when fitted in a BEC, which isn't ideal. It's not really a
case of squeezing more power out (at least not for me) but more wanting the engine to operate at optimum performance.
Power Commanders are just one way of acheiving custom mapping but there are other units available that do the job. Personally I have had no experience
of standalone ECU's so couldn't really comment.
If the engine is Suzuki, it's worth considering the FITunerPro from Healtech Electronics.

Bike engines are tuned to the restrictive exhausts and air filters to maximise power, if you change the application and the ancilleries then it will
definately need mapping to optimise, for myself junking carbs for EFI made it feel much faster in the earlier days.

I am only familiar with older bikes, but they seem to benefit from a little ignition advance and sometimes from revised trumpets. UK petrol is pretty
good quality compared to some of the markets that these things are sold in and air temperatures are generally fairly cool here too.
Remapping for custom exhaust and induction also makes sense.
I don't think that that are big gains to be made though as the manufacturers on the mainstream crotch rocket litre bikes have done as much as
possible as these bikes are all sold on "pub bhp" claims. On other stuff e.g. Bandit 1250, st1100 that are detuned a bit then I think you
could probably make better gains.
If you want to squeeze more power out, then really you want to be squeezing more oxygen in (turbo, supercharger, NOS).

You can often get the stock ECU reprogrammed also, eg on GSXR, but obviously need a dyno with the right software etc

i gained a fair amount below 6k when i mapped my twin tl1000s it was really short of fuel low down on the stock map without the standard airbox but
previous dyno sessions showed the fuelling pretty good at the top end on straight through cans and pipercross sausage filters

Hi Gordy
Have you done any mods to the fuelling/ air etc since you got the car??
The Power commander was originally mapped by Jack Frost at Holeshot on his rolling road @ 128bhp at the wheels. Apparently this is about as good as it
gets for that flavour of engine, with a power hike only really being possible by fitting a 1000rr engine- which is completely different!
On hindsight i should have gone zx12 when re-engining your car from a blade 893 as £ for £ would have been about the same! (your bespoke exhaust
manfold alone was nearly £500 :-( )

Hi Scotlad, not changed anything on the engine, only serviced it, just thought it might need a tune-up,
it's not running badly or anything. Did a few trackdays at knockhill getting down to high 58sec laps when pushing hard on clear laps, have
changed a few bits on car but nothing mechanical, car's been great will need to meet up, where about in Edinburgh are you?

Really? Does that depend on the ECU, as everywhere I asked quoted £80+VAT per hour and 4-5 hours mapping time from a base map. Hence I mapped it
myself.

Had mine mapped with a power commander by powertech took approx 1.75 hours and it was approx £150.
