converting my banshee to efi

[bansheeefi460]

i'm trying to get my banshee fired up rite now and i'm having problems! If anyone can help I'd really apperiate it! well I have a banshee built w after market exhaust, bigbore, coolhead, and stroked, and i put an set of R6 throttle bodies, w an aftermaket 155 lph fuel pump, and an adjustable fuel pressure regulator, and i'm running the microsquirt v3.0 on it. I'll I want is to be able to control the fuel w the microsquirt, I have calibrated all the sensor's and adjusted the pressure regualtor to 40 psi and found my flow rate for my injectors and have an ve table from a friend to give me a base ve table to start w. My problem is i can't get my banshee to start at all w only the microsquirt. I can hit the injector test button and i can hear the injectors fire and when i kick my banshee over it will start rite up off the fuel that was injected. And my tach on my laptop will read rite also. but, the injetors won't fire on there own and the fuel pump will only prime it won't run when the engine is started. I'm using the stock vr sensor connected to the vr input 1 and the flywheel is the stock 2 tooth flywheel. Can anyone please help me i've been working on this for weeks? thank you very much! brent I have below is my current tune

banshee,

You might want to post a datalog of a starting attempt. This will let us see what is going on. The fuel pump should be on whenever there is a tach signal, so if you are only getting a prime from the fuel and it stays off after that, then you probably have an issue with the tach input. A datalog will confirm this.

I agree with Lance, you're not getting a Tach signal to the Microsquirt (or more specifically, not getting it a Tach signal it can recognize).

If your Banshee uses Inductive ignition coils (not Capacitor Discharge ignition) here's a link to a very effective, simple, tested and functional direct coil-sensed Tach input circuit. Shouldn't take you more than a few minutes to wire it up so it would be an easy test/fix for your fuel-only application. I've been using it for several thousand miles now in my Kawasaki Ninja EX-250 fuel-only project bike. Remember, this circuit will not work with a Capacitor Discharge ignition system

Here's a link to a thread with the circuit diagram and explaination: http://www.microsquirt.com/viewtopic.ph ... 86#p151772

The circuit was originally thought up and drawn by forum member Matt_GSXR for use in the fuel-only phase of his development of a GSX-R1000 engine in his Phoenix race car. As drawn in the linked thread it is set up for a 4 cylinder, wasted spark, inductive ignition engine. But as you can tell from the discussion in the linked thread it can easily be modified for a 2 cylinder wasted spark or 1 cylinder engine.

And in case your Banshee is a Capacitor Discharge ignition here's a link to a guy who did a Megasquirt conversion of an RZ350 (which uses about the same engine as the Banshee I think).

http://www.smcomp.com/~smurph/RZ-EFI/index.html

He used a GM HEI module for his project's ignition. He explains it in his website's sub-heading of "installation".

[bansheeefi460]

thank you for the help so far guys! this is a log of my atempted start. And I did try the 4 pin hel module and couldn't get a tach signal to even register w the hei module inline. any other ideals guys?

[EWflyer]

Well, what's the answer, does the Banshee use inductive ignition or is it capacitor discharge ignition?

And you're saying that the RZ-350 installation website didn't shed any new light on your HEI module problems? No subtle differences in his install vs. the way you tried it?

[bansheeefi460]

Well i did some research and my banshee uses a AC/capacitor discharge ignition system. On the rz350 they use either a DC,capacitor discharge ignition or inductive (IDI) system. I've done the hei 4 pin module and triple checked everything, and it never worked on my banshee so i'm thinking that bc, the rz350 has either a DC cdi system, or an (idi)that has to be the difference between the two. And i'm wanting to say they use a (IDI) system bc, a hei module is built for a (IDI) system. Well I'm back to the drawling board, any more ideals? My ears are open. I do apperiate the help so far.

[EWflyer]

Wouldn't you have to change to inductive coils if you wanted to use GM HEI? Aren't the coils on a CDI system totally different in nature from inductive coils?

I might be wrong but I think inductive coils are hooked up to a 12 volt source and are triggered by a ground contact through the ignition system while in a CDI system the energy for the ignition coil to fire comes from the ignition system.

[bansheeefi460]

well i just tried the hei method again just incase i was doing something wrong which like i said, i triple check everthing but, yet still wasn't getting a signal. But, rite now i have the vr sensor spliced into and the vr input 1+- hooked up rite to the vr sensor, which this is what I have in my data log, and i'm getting a tach signal that way, atleast on my laptop on tunerstudio ms. But, from there i'm lost.

[bansheeefi460]

i hope you didn't missunderstand me. My banshee does use a CDI system. That's why i'm guessing that the hei module didn't work for me. And i can't use your idi system bc, my coil isn't triggered by a ground, it's triggered by, a source coil, capacitor inside my stock cdi box. So that's why i have my vr sensor spliced into, and running it to the vr1 input on the microsquirt v3.77. and i get a tach signal but, not a useable one. And i don't understand how i can change this?
