Ignitech CDI map?

Like I said earlier the stock tps map is just a generic thing, its not intended to work, you need to imvest in a lot of dyno time if you want to use this function and get it setup right.

Thats because these bikes didnt have a 3d map in the first place. 

Ignitech just supply a 2d map mirroring the standard curve that is ok to use as is.

If you making any changes to the map without doing it on the dyno then your pissing in the wind really anyway. I personally wouldnt want to be running 40 degrees of advance at low throttle openings, not likely to be doing your motor any good

Nah I'm going to change it. Again was looking at turbo maps which are for lower compression motors. Stay tuned for v2

Where you getting your turbo map from? 

My turbo ran best with a standard ignition curvre. But I had big intercooler.

Generally non intetcooled setups people end up with about -3 or 4 degrees off max advance to keep it safe

Just found them from googling 3d ignition map.

 

Had a few runs up the road today. This is so far the most responsive map, I've only been doing up to max revs in 3rd gear and trying to get the revs as close to idle when poodling around. Very smooth, very torquey and so far no nasty noises. Still doesn't behave amazingly well on choke, but comes off choke and idles fine after about 10 seconds. I took a bunch of columns out at higher revs as it created steps where as this creates a nice linear increase

Hello, gentlemen.

 

I own a b12 2001, with walker mod and ignitech.

 

Trying to set up the map, i came across this post.

 

Anybody would be so kind to share a good one with me?

 

Ignitech is really 0 cooperative, and cannot find anything on the web...

I just copied the dyna2000 map (if you Google dyna 2000 set up therespics of their maps) but I pulled 5 degrees out because turbo

Hi all, late to this party, but assuming a 2d map is RPM and Advance, what’s the 3rd dimension? TPS…? 

Soz if obvs

Correct.

could be MAP!

Do you have a map sensor on a carbed engine.

We're discussing  ignition units here

[ChrisK]

carbs… but I think I get the idea. 

Checked their website and don’t feel particularly confident about the maps that you get as a starting point. I remember some guy saying his tickover when cold was super high once he fitted one. That would piss me off… 

Either way I think I’ll fit it and book a dyno session.

anything that has a throttle blade can use MAP sensor! More accurate Actual load sensor compared to TPS!

[ChrisK]

is it only the 1250 that has these (fuel inj only) or do the carb models as well?

Later bandit 1200 had a TPS. never seen a map sensor on a carbed engine in anything.

the TPS on the bandit advanced the ignition at light throttle openings at higher revs, ie cruising to help fuel economy.

great thanks, I’m going for a mk3 1200 so will have a tps.

 

Any recommendations for a dyno centre in the UK//SE? I know there are a few out there…

No, it's not. At least as long as we speak about individual throttles per cylinder.

What makes you say that as I respect your thoughts. If taken from one cylinder I'd agree but through a smoothing / balancing tank, it should give stable enough depression for load sensing - don't one of the aftermarket ECU's use MAP to determine cylinder sequencing -same difference?

[Arttu]

Smoothness of the MAP signal isn't the problem. As you say it can be sorted out relatively easily. The main problem is that usually with individual throttles the measured pressure doesn't correlate very well with load / air flow. When you gradually open the throttle the pressure increases but reaches the ambient pressure (or boost) pretty quickly. Beyond that point there is no change in the pressure but actual air flow still keeps increasing while the throttle gets more open. Systems with single throttle and common plenum (=typical car engine) don't have this problem.

Engine phase detection with MAP is somewhat different problem. There you want a clear jump in the MAP reading during the intake stroke but accuracy of measured pressure isn't important.

So, effectively a MAF sensor may be a better choice? I know Bosch used a MAF system in a lot of their designs - obvious advantages!

In theory, yes. But they also have their own problems why they aren't the best solution for modified engines. Usually combining TPS and MAP in some way is a good solution for bike engines.
