Ignitech TCIP4, again

[Speeddog]

I've got a pretty good loop for commuting, 100 miles round trip, about 65 miles highway, 30 miles farm roads, and 5 miles urban.
The bike's pretty consistent on mileage, and traffic's pretty consistent as well.

I've got one steep and long hill on the highway going in, I've got to get a good vacuum reading on that.
I don't think I could hear it pinging, and I'd rather not injure it...

GM green, eh?
I'll see if I can get one of those for a decent price.

Hi,

sorry for interrupting but can anyone tell me what would be a good map for a Monster 600, carbed - stock?
And if could someone explain how these advance values influence the running of the engine - I am trying to understand how it works. Sorry for the noob questions.. 

[brad black]

maybe like this one?

maybe by green I meant black.

Which 600, left or right side clutch slave?

I have a '96 600ss with the right hand side slave and I have the ignitech fitted.  I used the 1.1 curve as a starting point and tweaked it here and there.

[Speeddog]

Generic GM-style MAP sensor, same as what's on my Saturn (seemed a good idea to get one that I could re-use if necessary).

Appropriate pre-made connector and pigtail.

Only needed to attach the terminals and stuff them into the proper spots of the Ignitech connector.
Well, that, and piggyback the two trigger ground wires onto one terminal, as I needed the other one for the MAP sensor.
Ignitech took the easy way and used up both sensor grounds with their harness.

Very cool. Looking forward to the outcome.

hi, it's from 2000, clutch slave on the left. would you mind sharing your version? your bike is stock?(exhaust & intake)

Thanks!

[Rudemouthsky]

Pardon me;

I'm hooking up my own Ignitech today or tomorrow. Skimmed the entire thread, wasn't conclusive. I have the CA-Cycleworks Exactfit coils with the wires Chris supplied with them. I will be using the NGK-DR9EA plugs. Are the wires that come included with these coils the ideal non resistor type? Just want to be sure I have the right setup.

thx

[ducatiz]

Plugs are resistor.  You're good.

Thanks!

shoot me your email.  Mine is not stock at all but that should not matter.  600 and 900 use the same advance.

Hooked the whole kit with the MAP sensor back into the bike, plugged it into the laptop and gave it a look.

Straightaway, ran into a rather big problem.



Voltage vs. Vacuum curve for the MAP sensor is great.

However, the IgniTech won't budge off of 100% TPS until 5 inHg (~3.8V).
That's not good.

I've got to spend some time talking to a sparky to figure out if there's a workaround. 

[brad black]

you set the tps min and max voltage to wtf you want in the ignitech set up.  misc (1st) screen, select the tps yes button to make it appear.

that should make it work from my experience.

of course, if what i'm saying is not what your issue is, ignore as required.

Yah, that's what I did.
Enabled the TPS, then hit the 'SET TPS 100%' button with the the MAP sensor open to the air.
Then put 20 inHg vacuum on it, and hit the   'SET TPS 0%' button.
TPS% wouldn't come off of 100 until the voltage got below ~3.8v. 
I altered the TPS max voltage up and down, but it wouldn't budge off of 100% TPS until the sensor voltage got to ~3.8V or less.

[suzyj]

Ya just want a divider to reduce the voltage a little to get it into the TPS range - it depends on what the input impedance of the TPS is though.

I'd start with something like 330 Ohms in series with the sensor output (between sensor output and TPS in), and 1K from TPS in to ground.

Season to taste.

[Speeddog]

I knew suzyj could guide me out of the wilderness!   

Wired in a 2.5 kOhm trimpot as a voltage divider, did a bit of adjustment, and it's really good now.

New graph, not all that exciting really, but I took data to confirm function, and you must have a graph to show results to the boss. 



As an added bonus, in the process of sourcing the trimpot, I found the awesome electronic supply store I've been looking for for years.
They've got a 10' x 10' wall area just for zipties, it's like a freaking candy store. 
No more trudging to Radio Shack to negotiate with ignorant dolts and buy total crap.
I can go to a real store with knowledgeable staff and get quality parts.
