The Ignitech is a sensitive unit. Mines in the tail, wires away from the HT leads. You have to also have the correct plugs as it doesnt like the wrong ones, I think its recommended by Ignitech to have non resistor? Have you had the map done as it makes a huge difference. The TPS zero'd properly? Theres loads of wee things that can affect it. The more we mess with our bikes the more complicated they become. Having said this, it could be the carbs, but if it runs ok with the Kukosans, its more likely the Ignitech or electrical..
It's not the carbs!! They have been stripped completely, new seals throughout, new emulsion tubes etc etc, completed by a specialist so i know its not them and as the bike runs fine on the stock Kuksans this confirms it. So it must be something with the ignitech/tps how i have set it up/installed it etc. My unit is in the tail also. Yep no resistor plugs I think, will double check this. Are the stock plugs resistor type?. I susspect its something to do with the map and the tps settings. It's only running the stock map at the moment, when i bought the unit i told the guys at Ignitech what was on my bike etc so they could map accordingly. Whether or not its different from standard I have no idea. Next step was going to be to disconnect the TPS physically and the setting from the map and then take it for a run. This will either confirm its the TPS or the map/unit etc.
Go to Ignitechs website, download the standard map for the Kukosans which they come loaded with from the factory, and compare it to the one you have on your Ignitech at the moment. You may be wise to download this map onto your Ignitech and then take it to the tuners for setting up. You telling Ignitech what you have and them setting up a map is not an effective way to get it to run best. I had to take mine to a rolling road and its been well worth it as I have a good few mods. Taking the TPS out the loop will certainly narrow things down too
Update again...it's the TPS, either the unit or wiring. Took the bike for a run today with the TPS disabled and running the stock map supplied by ignitech and she ran great, better than the stock kukosans for sure. Smoother power and more pickup evrywhere!! So just got to figure out whats going on. The TPS came from Liam at Fastbikegear and the ignitech pre wired from ignitech so assuming both parts are good it could be the way i have wired up the TPS at the TPS end. But can't see how this could appear to function and not if you see what i mean.
Sev - TPS is moving properly on the spindle and when setting it, its giving roughly cause i can't remember 0.014V @ 0% throttle and 4.1 ish volts at 100% opening and sets ok with the software.
It’s been a hot day, it will run fine being on the lean side, last time you tried it out it was a freezing cold day? Worth a thought! One of my Duc’s is noticeably different from hot to cold days. Do your comparison runs the same day.
As per my finidngs when I set mine up. Essentially the TPS is just a resistance track, if there was a manufacturing fault you may get a blip in the middle potentially? Which would give you a problem at certain revs regardless of speed/gear.
Good point Paul, will do! Will test test this out when i enable again, if its happening at certain revs in a couple of different gears it could point to the hardware!! Cheers all
Update: ....Ok still getting an issue with my ignitech unit and TPS setup. A quick question to those running this setup, can i ask what spark plugs you are running with it. Just looked at mine and they are NGK DPR8EA-9's which seem to be the resistor type. The Caps, leads and coils are from Exige ie the CCW high out put coils which according to the spec have the same resistance as the original coils/leads etc. Just now wondering if this is my issue?
Sorry, I can't comment on the TPS, but My 97 M900 fitted with the ignitech unit, and Exige CCW Coils runs better than it ever has. The Spark Plugs are the ones that came with the coils, and I've just plugged in the Ignitech with no re-programming. The only problem I had is when I tried to tidy up the wiring and re-bundled it behind the coils. It ran like a pig all of a sudden, but was fine when I moved it all again, leading me to believe the system is sensitive to interference between the wires for the two pots if they are too close together. I've got some decent shielded braid at work that I'm going to cover the cables in. Nasher.
It is a sensitive unit, I earthed a braid around the Ignitech loom. Keep well away from HT leads. Im soon switching my CA Cycleworks coils out for Nology profires and using a Hall effect system supplied by Liam Venter in NZ.
Think i have solved it!!!...and yes it seems to be a sensitive unit! Changed out the plug caps to non resistor type and also swapped out the HT leads for some Multi Stranded Copper Core leaving the resistor NGK plugs and it seems to have done the trick. Took it for a ride without the TPS activated but just on the base map and she was pulling like a train cleanly at all revs. Then took her out with the TPS activated and same again although I now think it would benefit from a dyno session to dial in the map. Fingers crossed thats it!!
Nope.. thought this was sorted but took it out a week or so ago after getting it taxed and she ran badly again!! Only seems to happen at higher revs (6k and above) and on a constant throttle, surges and misses. Came back swapped out to the standard kokusan's and she runs smooth as, but has noticeably less go!! Will look at the shielding again and maybe the earth point and have another go, bloody annoying!!
Maybe, but can't see that sorting the constant throttle thing, as its been said before i think its sensitive to interfearance!!
Finally sorted...spent some time re routing the feed from the pickups so that it was as far away from the HT leads/caps etc as it could be, routing it up on the right side of the bike. Ignitech unit mounted in the tail and wires from that down the left frame rails. Also adjusted the FCR's to get rid of the hanging throttle and she rides really well now. Going to get it on a dyno come the spring to dial in the map and carbs....bloody awesome.
