Standalone ECU ( UPDATE Its Alive !!!)

[Gsxturbo]

Thanks OZ i will go over them and see what the differences are between the the two harness pin outs.

[Gsxturbo]

Well i got a little farther today on the testing for the standalone i got the bike running with both the MS1 and MS2 processors (Fuel only) today still need to get the fuel tables a little better tuned in but i spent about 5 minutes with the table generator and the bike fired up first time no problem so once i get the fueling a little more sorted out i will move on to the Ign. side of things.

Have you seen the std ecu ign tables Petrik has posted on SHOrg in the all motor  section, only thing he is not sure of is the baseline , need to compare a table with an actual timing figure . The neutral/clutch table would be easiest, i have an adjustable timing light but no running busa atm.

No i havent.

I am a member of Ridge racer and his website (i guess ) ECU Hacking i should look closer when i get back on there. I may try to get some timing figures from the stock ecu i have a dial back timing light so i may be able to get a few figures from the stock ecu settings and see if they match up to what Petrik got out of the stock ecu.

 Hopefully sometime this week or next weekend i will start on the ign. side of this and see what problems i run into i know its not going to be as easy as the fuel side was.

I also went and loaded the newest code for the MS2 in the chip tonight and went back up to the shop just to see how well it would start and run and after about 10 minutes i had real good throttle response and it would fire up better than the stock ecu so it looks Real good on the fueling side of things i havent even touched the enhanced Accel enrichment settings yet so i know with some tuning it will run real good , and i may have to set Alpha n blending but i dont know yet this is purely speed density so far.

Thanks for the link it look like a ignition map to me thats some real good info.

I got the igniter's for the COP coils done last night and ran them for a while on the bench they seem to spark real good so we will see if they work at least as good as the stock ones do.

Sometime this week or next i will get the trigger events for setting up the MS for sequential and wasted spark both, if i go with wasted spark you will gain two extra outputs that would be taken up by the spark outputs but i dont know if i will run into overlapping dwell problems or not running them in wasted spark, the good part about wasted spark is any 01-07 would only need the crank trigger as it already has a 24-1 crank wheel, COP will need both the cam and crank trigger to work.

 99-00 would need either COP or a different crank wheel to set up as wasted spark you could do it with the second cam trigger but the added signals could prove to be difficult.

Im staying optimistic though i think with enough work the crank and cam signals can be reliable i just dont know how hard its going to be either rewiring them or shielding them real good.

[Gsxturbo]

I think im going to concentrate mainly on the MS1 from here on out on the ignition its just to hard to go back and forth between the two they are very different processors and since most people already have the MS1 i will get that going first then i ill go onto the MS2 and get even better control over everything.

Once the MS1 is done the MS2 shouldnt be hard at all to get it up and going since i already have a base fuel map that starts and runs.

Well i have got a little farther with the ignition side of this i got both the cam and crank sensors hooked up and i am able to get a proper cranking rpm signal from them so hopefully tonight or sometime this weekend i can get it started and  controlling the ignition.

 I am using the 8 gap wheel right now as soon as i get it started and running i am going to switch out the 8 gap for the 24-1 and see how it does.

Cool stuff, you dont screw around do you?  Very nice Tony

[Gsxturbo]

Thanks im not that fast i just had some spare time this week during the evenings.

I had some spare time last night after i put together a busa head for a customer and i wired up some of it just to see if i could get any kind of rpm signal and with some work it seems to be pretty clean so far but until it starts and runs i wont really know how clean the signal actually is.

[Gsxturbo]

Well i got it running tonight with both fuel and ignition control it still needs alot of work but it does run with it.

Im going to use a different VR sensor circuit then what i have right now im getting some RPM spikes while its running witch is causing some sync problems but i think i can figure it out once i get the other circuit built .

This is with the stock crank and cam sensors and the 8gap wheel i havent tried the 24-1 yet but as soon as i get the spikes fixed i will move on to the 24-1 then i will go to the MS2 and get it going.

So hopefully in the next 4-6 weeks i can have it going full standalone and then i can get some datalogs when it gets warmer and be on my way to sorting out everything for the interface board and order the first batch to test.

[smithabusa]

Cool I have been waiting for the email update on this one, was happy to see it this morning.  Good job, sounds exciting Tony

[busa2001]

very good....

[kurtsbusa]

sounds like a nice set up you will have when it's done

[Gsxturbo]

Thanks guys. Im going to work on it a little more tonight and see what i can come up with on the tach spikes i got some ideas but i will see what happens.

The best parts is anybody who already has one of my secondary boxes or builds there own MS1 can do the same thing im doing right now with what they already have (some additional circuits are required).

Badass work man, I just found this post and read it.

I had followed the MS some time ago, but lost interest, Pinky and I discussed them, but I wound up with a complete Microtech Setup for a song.

I will go the Standalone MS route on my 2000 I am sure, then get rid of this Microtech to someone else who wants to turn up the wick.
The 8 Gap wheel is where you are starting, I have a 24 wheel I believe it is off a 2001 crank I had bought as a spare backup, so I can possibly swap it out and go that route if need.

Keeping this post as a shortcut on the desktop -

Keep of the good work

Yes i started with the 8 gap wheel first i know  alot of people dont use the older wheel as the 24-1 was used for more years but i think it will be the hardest to use seeing as the teeth are unusual on it Vrs. the 24-1, the teeth on the 8 gap are 45deg long instead of about 4deg long on the 24-1.

Im also doing both because i want any body who already has either the 8gap or 24-1 wheel that they can use either one they want without having to buy a certain wheel and all you would have to do if you had a 8 gap and wanted to use a 24-1 is change the crank trigger settings in the software and you ready to go takes about 2 minutes once i get both of these set up and have the settings.

Well i got some very, very good news last night i was chasing some false triggers or spikes around while messing with it , and tonight i reworked my VR sensor conditioners a little, and tried it again it got rid of the spikes but it still didnt sound nice and crisp so, i was thinking maybe the stock system conditioned the sensor differently then the way the MS or my conditioner was doing so, on a hunch i switched the polarity on the crank sensor, and wha la there it was run super clean , and sounds really good i can free rev it all the way to redline with no misses or drop outs so it a big step forward for this.

I found out i have a bad coil driver so tonight im going to fix that , and later this week i will continue fine tunning the cold start settings, and  then i will tackle the 24-1 wheel.

 The good part is once i have all the crank settings for the MS1 the MS2 settings should be a breeze i think, because it does all the wheel , and teeth figures in the software for you plus it is twice as fast at processing all the info so it should be even better than the MS1 for what i am trying to do, but i want to show that the MS1 can be setup to do it if you want , and thats what the secondary controllers i build have in them so they would be easy to convert over to standalone if someone wanted to.

I now what you mean Ron the MS turns alot of people off just by the fact that you can set it up any way you want , and you have to build all the circuits yourself thats why im doing all this i want anybody who wants the option to use it this way there, so if they want to they can without having to buy a whole new system

The MS is a great learning experience for me and ALOT of people around the world and for 140.00 for a standard 2.2 boad kit you cant beat it im no expert at all when it comes to electronics i have burnt up my fair share of stuff , but i learn something new everyday on these things , and i have been messing with them for 6 years now and believe me in 6 years these things have come a LONG way software wise from when i first started.

 Thats why i cant stress enough to people if they try it go ahead its not that hard to get started and at times things are hard to track down but if you keep going , do some reading on the MS forums ,and ask some questions you will be amazed at what these things can do for little money hell there is a guy making 1000 or more Hp out of 4cyl with just the MS1 so dont under estimate it.

Now im buy no means trying to toot my own horn i have no idea what this thing will do till i get out on the road and start tunning i might run into problems that will set me back weeks to track down but i will keep going till this is done i have wanted for so long to get one of these to work as a standalone so i will finish this sometime before i die i hope.LOL

All this will benefit anyone who wants to use it this way and when i get the interface board done it will be a simple plug and play setup i hope, even if i do have to pay 2G for 500 of the damn connectors (the supplier still hasent got back to me on them yet)

Thanks guys for following my work its nice to come in from the shop and see people actually care about this and show interest in it and to OZ for the tip on the crank and cam sensor heads up.

I am just waiting patiently for the results to see if i want to tackle modding my Mini-MS that I built quite awhile ago to run the Busa...

can u run 2 sets of injectors or would u need to keep stock ecu for primaries
