I'm planning on getting a custom map done. There's a few Dynojet centres around, there's one close by that I know nothing of, and there's a couple further away that have good reputations.

Does the quality of the map depend on the skills of the dyno technician? Will I get identical results if I take the bike to two different dyno centres? Or should I take it to the guys that have a reputation for doing the best work?

Ta, in advance.

They're all meant to be trained to a very high level (DynoJets' words, not mine) so they should all produce exactly the same map for a given bike.

I'd go for the one with the most experience though. Training is nothing compared to solid experience.

The map you will get will depend entirely on the experience of the technician and his skill. You could go to 2 different centres and get completely different maps! I can recommend you a place in the south...?

Depends partly on the powercommander being fitted, if its a PC111, PC111R or PC111USB, dynojets tuning link software takes over and does most of it, the operater enters/follows certian parameters about the make and model of bike, does a group of runs and the sofware builds a map to correct the differences. However there is no substitute for experience

sorry - this isn't quite true, you've been given duff info. A tuner may start with a map which he's created from a previous customer with same bike make/model but the software doesn't take over and do it for you. You start with a blank sheet, so to speak. He can then "tweek" his previous map to your bike so you get a unique map for yourself ie to match your engine, exhaust system etc. I know this is true for a IIIr (USB or not) as we run one.

Absolutely true.

Hope this helps,stu

By utilizing the Dynojet "Real Time" air/fuel ratio monitoring equipment and latest "load control" Dynamometer technology, the Tuning Link monitors the current air/fuel ratio at over one hundred and forty different points. At the same time, the Tuning Link automatically calculates the correct fuel adjustment to achieve the user desired air/fuel ratio. Once calculated, the Tuning Link uploads these new fuel values to the Power Commander and saves a copy of the file.


That sounds like the tuning link does create the map automatically. Not everybody uses the tuning link though.

What I was trying to say was that it shouldn't really matter who is doing the mapping as the tuning link sofware works to correct the fueling to a specific A/F ratio rather than the operators judgement, so you should get virtually the same results on different dyno's

My advice: Don't believe everything you read on the tin!

Thanks for your inputs, everyone. Given the money I've put into the can, air filter and PCIII it seems false economy to go for anything other than the best tune I can get.

Stu, I'd guess your recommendation is Gary Teague? He's a little further away for me but my mum's just round the corner so I can kill 2 birds with one stone, so to speak.....

You have to get all your new expensive bits and bobs tuned in to your bike. It must be running very "fluffy" at the moment?

Gary T is excellent on a dyno, he knows his stuff and I would personally recommend him. He doesn't use the latest all singing lovely dynojet machine (cos he prefers other stuff) but he has done all our bikes and many more besides - I'll PM you "Dr Suzuki's" details etc

I've just got back from Gary Teague's dyno shop.

The map I'd downloaded from the Dynojet web site wasn't right, despite the fact that it's labelled for the exact same bike, same can and same air filter.

He found me another 7bhp peak power, but that's a little irrelevant and the bike's never been short of power. The biggest improvement is at small throttle openings in the mid-range, which is where you are when just rolling on the throttle when cornering. The downloaded map was making it run too lean, which made it snatchy, now the off - on throttle transition is smooth and linear.

A much nicer bike to ride.
