Hayabusa Interface Board RUNS !!!!!

[smithabusa]

how are you adjusting the shift kill etc?  Something in the original software or do you have new software that interfaces with it?

[Gsxturbo]

One of the two SX microprocessors is hooked to the ignition drivers and by activating the input pin it will kill the drivers for a set time it also activates the shift solenoid with a kill delay built in to give the solenoid time to get the air to the shift ram.

You adjust the kill time and kill delay with dip switches and you can change the kill times and kill delay in software too but you will have to have a key to do that.


The two processors have 20 configurable I/O pins the one for the kill uses 10 so 10 are left over for other things if you wanted and the spare processor is not hooked to anything so it has all 20 I/O free to do whatever.

Damn thats cool

[Gsxturbo]

LOL i will get some close up pics of the processor with some illustration later for you,i dont have the dip switches mounted yet but the outline on the board is there.

[jasonsbusa]

This is pretty impressive.Good job

[Gsxturbo]

This is pretty impressive.Good job

Thanks. I am going to post up some pics of the IB (Interface board) close up so you guys can see kinda how the inputs and outputs will hook up to the IB from the MS .

[Gsxturbo]

Here is a pic of my test setup so far and you can see kinda how its setup the MS plugs into the 24 pin AMP header and my jimstim hooks to the stock 60 pin ecu header for the signals the close ups of the board i was going to post are to big to post so i am sending them to you guys who want to see how it hooks up and study if you want.





This board will be a great learning tool for those who want to explore electronics and learn some things ( i have learned alot so far my self LOL) it is really flexible on how you can set it up and what you can do with it ,it wont do everything but it does quite a bit and alot more than some people would even use.


This is still in the experimenting stages so dont think im saying this is tested and done and no problems have been found because until its hooked to the running bike i dont know exactly how it will act it should be fine but the running bike will tell the story.

[smithabusa]

The pics you sent look sweet!

[Chris Horoho]

what pics i wanna see lol

[Gsxturbo]

The pics you sent look sweet!

Thanks i had to change the setup on the dual processor board so dont worry about those pics i sent (orange wire) the new ones would be different any way.

[jasonsbusa]

Whats the plug sticking out the side of the MS for?

[Gsxturbo]

Whats the plug sticking out the side of the MS for?

For serial connection to the slave processor .

[Gsxturbo]

Well i haven't messed with the Interface board too much but i have been working on the spare Micro that is on board the Interface to accept the stock GPS sensor for feed back and so far i have 5 of the 6 gear positions working im still working on the code if it works i will incorporate it into the generic PWM program for use with a boost control setup like Greg sells so you wont have to mod the GPS sensor to use it just plug it in and it will recognize the sensor and what gear it is in  then you can set the ramp rate for each gear and solenoid
Now this is all in theory so it might work and it might not.

[Gsxturbo]

I made a little progress on the program for the GPS and the PWM so far i have two stages for the first two gears setup and working and i added an output from the autoshift/autokill micro that will reset the position between shift and gear positions so far it seems to be working real good now i just need to add the rest of the program for the other 4 gears.

[OzBooster]

What solenoid are you PWM for the boost control?
I have used a MAC 35  before   they come std on the e-boost 2 i'm using

[Gsxturbo]

Im not sure what solenoids Greg uses with his boost controllers but those you posted should be fine i just need to find the frequency they work the best at and adjust it inside the program.

[Gsxturbo]

Well i have the Interface board running on the bike !!!

I ran into a little trouble with the cam trigger signal to the ECU i chased that problem for about a hour then i changed a resistor on the incoming signal wire from the cam sensor and all was well it synced right up so i moved on to testing the coil outputs and ran into another problem when all the coils were plugged in it kept loosing sync so i removed all plugs and re gaped them and fixed that problem ( i really should have put new plugs in) i went through a few settings and it fired right up.


I still need to see exactly what the timing is set at but it fire up pretty well and seems to run fine the timing map right now is set at 10deg everywhere just to get it started and running once i get a timing light and see what it says.

This is with the MS2 processor installed and im running extra RC1C code im going to back up a few codes and see if its more stable this is real new and the rev limiter seems to be something funny it works at first then quits.

This is also with the 8 gap crank wheel installed i will go to the 24-1 next and see what it does .


Every stock sensor is still hooked to the harness and the CLT and IAT sensors seem to be pretty close on the temps but i will scale them so i can use the stock CLT sensor i will use the open air GM type for the plenum but leave the stock pig tail this way if i ever wanted to put a stock ECU back in it will take about 5 minutes to change over and go.


My recommendation for the main processor will probably be the MS2 once i get a stable code installed and if you need more outputs you can use the dual processor board with a MS1 for the more options.


All and all im pretty happy so far but more testing is to come to make sure it works like it should but this makes me happy so far.

[smithabusa]

very nice, i am excited as hell about this

[Gsxturbo]

Yeah i was very happy that it all worked as good as it did for the first start up, for this being my first circuit board design it works very good so far.

For the Next run of boards im going to make some changes and update some stuff i may sell these boards as Beta's to testers if there is enough interest .

Dont worry Greg i still have a board set aside for you.LOL

I have a scope coming in to start working on the CLT gauge next and see if i can get that working the Tach works smooth as silk.

[Chris Horoho]

is there any delays in the tach luike the factory ecu was?
i believe they are close to 500 rpm off?
