M150 Ref/Sync for Hayabusa Gen1

[uaeproz]

Hi Guys,

I'm hoping one of you or Motec support guys would provide some support and would be appreciated.

I just bought brand new M150 from the dealer and I'm lacking support with the startup ref/sync file. I just need a startup file, can somebody help... Please?

I'd appreciate any help here.

Thanks,

Abdulla

I'm lacking proper support from the local Motec dealer over here. Can anyone at Motec at least provide some support?? I made huge investment buying Motec products and at least I would expect as an after sale support is a startup file? This is what I bought from Motec so far:
Hayabusa Gen 1 motor
MoTeC M150 with GPRP license
MoTeC PDM30
MoTeC IGN4
Motec c127
MoTeC gear box control paddle shift auxiliary kit
MoTeC Oil & fuel pressure sensors
Wideband
Several motec looms
Bosch fuel pump

I'd appreciate your help.

Thanks,

Abdulla

You should use M1 Tune (v1.4+), to do Online -> Capture Inputs…

I think the Ref/Sync is probably something like: (this is for a GSXR1000 / K8, which I believe is similar to a Busa Gen2).

Engine Speed Reference Mode : 2 - Crankshaft two missing 4 stroke
Engine Speed Reference Tooth Count : 24 — this is for a Gen2, and I believe the Gen1 had a different tooth count 30? — you can figure it out from the Capture Inputs…
Engine Speed Reference Offset: 442 deg (but you should also try 82 deg in case the cam timing was not set properly) - I have one file showing 102deg?
Engine Speed Pin Pullup Control: Off (Mag sensor)
Engine Speed Pin Active Edge: Falling Edge

Engine Synchronization Pin Pullup : On (Hall Sensor)
Engine Synchronization Pin Active Edge Rising Edge
Engine Synchronization Pin Threshold: 2.0V
Engine Synchronization Pin Hysteresis: 0.5V

The Gen 1 had a 24-1 crank trigger wheel, so 'Crankshaft 1 Missing Four Stroke' would be the correct mode.

Also, the M84 start file has a CRIP of 462, so for M1 this would equate to a Reference Offset of 102 degrees.

Otherwise, an input capture would be the next step to allow the ref and sync to be correctly configured.

My M150 is with GPR-P package for the paddle shift function

Here's an update,


We've tested the setup that was recommended but, it doesn’t lock. We changed the setup and it locks but still not starting up.

I have attached the files. I’d be grateful for your help.

Thanks,

I know this is a 9 year old thread, I ran across it looking for something else. I figured I would give some relevant correct information in case anyone else finds this thread looking for Busa Ref/Sync information.

Gen 1 Busa has a mag cam sensor, not a Hall (this was probably the issue with the setup discussed in the thread, no final solution was shared). The 99-00 Busa has an 8-0 (8 tooth no missing) tooth configuration, while the 01-07 has a 24-1. The zero crossing of the cam from the factory occurs during the missing tooth on 01-07, which is an issue for the Motec Mx00 gold boxes. It is also an issue when changing cam timing with an OEM ECU, as a large change can move the cam signal outside of the missing tooth window, causing an ECU error.

Gen 2 Busa has a Hall cam, mag crank, and a 24-2 wheel.

Gen 3 is the same ECU settings as Gen 2, but most parts are different.

CRIP value for all 24 tooth wheels is 102, sometime you need 462 depending on the cam trigger setup. I think the 8 tooth also had this CRIP, I can't remember it has been so long. Every Suzuki from this era and newer we ever did had a 102 CRIP, so if you don't know, 102 is a good guess.

The Gen 1 cam sensor (mag) has a 2 bolt mounting configuration, while the Ge2/3 (Hall) have a 1-bolt, so they won't interchange. But the 2007-2008 GSXR 1000 has a 2-bolt Hall sensor that bolts directly to the Gen 1 Busa valve cover and triggers perfectly. This how we got around the Mx00 issue. With this setup one side of the Hall trigger may still inside the missing tooth window, depending on cam timing, but the other one will be outside. Take a ref/sync capture and figure out what cam setup setup (rising or falling) is needed to be outside the window, and set the CRIP to either 102 or 462 depending on which side of the window it occurs.

If you don't understand the significance of the above, the Mx00 was originally not capable of handling a cam trigger during the missing tooth window, so there was no solution with the Gen 1 OEM mag sensor other than relocating the pin in the cam. Motec later updated the Mx00 software to include a mode with the cam trigger inside the missing tooth. We never used it as the same issue as OEM, that is the very narrow 15 degree cam timing window can cause problems. None of this is an issue with an M1.

Maybe this info will help someone some day.
