Scooterotica

is there any info on the Mtec online?

I been looking around and all I found was place to buy it but no real info

this agusto unit sounds great, as I understand it offers 6 degrees of swing, so am I right in assuming that in theory, if my normal "cruising speed" occurs at say 6500 rpm, I would set it up to give me my required 15 degrees at 6500, and that results in it being setup at static 21 degrees

I have just found the info sheet about the Mtec on MB's site, that looks more useful as you could just select the range that gives you say 5 or 6 degrees retard, and set the static accordingly, thus avoiding the possible problems that I read of on this thread with a wide range of retardation

Agree. 16 settings....bliss!

How many of them are actually any use though?

Well you can only use 1 at a time. But when setting scooters up on the Dyno I use a variety of settings depending what the motor is, what pipe it has and so on.

The mtech shud be supplied with a jewellers loupe to see the dial!!! lol

The end with the arrow head gets mashed quickly too, so rely on watching the strobe to see which end the setting is at.....

Contact Martin at Chiselspeed, very approachable and happy to chat (at least by email in my experience) and gives excellent service.

just a quick thought but is anyone using varitrontics having issues, don't seem to hear any moaning from them but they are surely at the mercy of the same laws of physics

I'll now need to do a load more miles, road testing, EGT monitoring and possible adjustment before I am happy that all is well (along with doing the same with a 6000 unit for comparison).

FYI - I could only seem to get 4 degrees of variation from it (tickover to max revs, which on the stand were well over the 9K max on the road) so currently have it set at 18-14, based on the fact that it ran 16 degrees static.

Interesting to be playing with something new though and initial impressions are good.

Don't know what timing light you use Adam, but maybe this could be the reason you only appeared to get 4 degrees variation. I had a similar experience with an Mtech and Martin at Chiselspeed checked it for me and found it was OK.

Refering to timing lights:
"And the key here is "cost effective". In some instances, a trigger delay is installed in the light (this practice is even found in some very high dollar “professional name brand” lights. I won't name them. Just think mega bucks). This has little effect in the lower engine speed ranges, but once the RPM level goes over the 2,000-RPM range, timing lights with delay circuits appear retarded."

I know my timing light is both cheap and ancient and while it may be fine for setting static timing, it may not be up to checking the dynamic timing at higher revs when using an Augusto/Mtech or similar unit!

I realise that the timing light "problem" mentioned above should infact give more "degrees movement" (I think ), but I think that it is indicative of the fact that all timing lights are not necessarily as accurate as we might expect, especially when trying to plot ignition retard at higher revs.

well during a tour of the west coast of Scotland on very slow roads I had to disconnect the augusto 6000 unit and guess a safer setting (20 btdc as it turned out) as I had major overheating, it seems that pottering at a slow pace was not allowing the ignition to retard to a safe figure, this leads me to conclude that without setting up on a dyno this device is no use to me. I fitted it to make the motor run cooler and save fuel but it seems to only work when you nail it, so sadly I don't think its for me

I'm now playing with a 6K unit and it is giving a wider range of retard, with it happening sooner in the rev range (as to be expected compared to the 8K that I had on previously). I still need to do plenty more setup miles before I am happy with it, noting higher temps on my EGT now, but it gives me something to tinker with.

As Dave has said above, I do think that some people are 'making light' of how much attention needs to be paid when setting these up, otherwise they can do more harm than good. That said, I am convinced of their benefit potential and now need to realise it for my own machine.
