Is anyone on the forum running MSnS (fuel and ignition) on an S5 TII without problems?

Or just fuel and using the stock ECU to control ignition?

 

eage8 will soon be running it on his s5 TII

 

Ignition as well? I'd like to see it done before I pick up my TII and decide whether or not to go with megasquirt... I don't like to be my own guinea pig =p

Anyone running just fuel on an S5 TII?

 

hey buddy, did you end up buying that black 89 TII?

 

I think I am going to get a kit here pretty soon. Fero313 is going to put it together and I hope to get a plug and play adapter.

 

Keep me informed man.. so Fero is gonna solder it up for you and you plan to plug your stock harness into an adapter, then into your MS? Sounds appealing to me. Has fero had any experience with the ignition aspect of MSnS though? The fuel controller deal seems to be fairly set in stone, but I've yet to see anyone on the forum run the ignition from the MSnS without problems.. good luck!

 

I run ignition without problems on 3 rx7's...

tofuball's works great with the proper firmware, and the two test cars work great as well. Both of the cars I test the plug 'n play units on fired right up no problem the first time I tried.

Most of the problems are due to wiring, and the fact that it's DIY unless you get someone to build it for you and make it plug 'n play.

 

Just the information I was hoping to hear! I've been following dDub's build, as well as 88IntegraLS's, and they ran into problems with their ignitions, and thats all I've heard on that front. Just about scared me away from MSnS..

I don't have a problem with wiring, but I have very little experience with soldering. I'd like to build the whole thing myself but I don't want to spend the money and the time on a project like that if I'm just going to screw it up. Any suggestions on gaining some experience with electronics and soldering? Should I take a class next semester in circuit construction or something?

Given I do figure out how to build it, and hook everything up properly, I have ZERO experience with tuning. If I still had my NA, I wouldn't be too concerned with blowing my motor with a slight screw up in tuning. Unfortunately, I'm not sure that I could afford to blow a TII motor and rebuild it. Any suggestions there? I don't know of any MS experts out here in CO that could help me out..

 

I'm not sure what's going on with 88IntegraLS, but ddub's problem was because I took out the LED's on his MS... when they were put back his ignition worked fine.

soldering is easy. just buy a perfboard and some resistors from radioshack and practice a bit.

My recommendation to avoid cold joints is to put the soldering iron on the component to be soldered, and touch the board a bit too, then on the other side of the component, touch the solder to it... as soon as there's enough heat, the solder will melt and you can stop. This avoids putting the solder somewhere where it's too cold for the solder to "stick," thus avoiding cold joints.

IF you're that scared of tuning, take it to a shop and let someone else do it. If you really want to do it yourself, go to www.megasquirt.info and read all their tuning info. Just read the whole site. There's good info all over the place there, even if you're not going to use it all it's good to know.

 

He isn't going to do any tuning or set up, that is all on me. But he is a master at soldering PC type boards. He did rotorbrain's TechEdge Wideband for him. I had him check out the info on the MSnS to see if it was overwhelming or him, but he said it looks to be 2/3 the work of the TechEgde. I guess that means he thinks it is easy. After he does mine he might start assembling them for people.

 

the v3 board is about the same as a techedge, I've done 2 techedge boards at this point, and while the parts are crowded, the actual number of parts is about the same.

The techedge is actually easier if you consider the custom mods that you have to do to the MS and the extra board you normally have to add to get it all working.... there are no "custom" mods necessary to make a techedge board work.

So from what I understand from the FAQ (for my S5 TII) I need:
Megasquirt II v3
*errors daughterboard for the ingnition
harness (hint hint)

I'm not running any emissions at all, so the wiring should be pretty straight forward.

I am worried about things like IAC, TPS and cold start since I have nothing to compensate.

 

I'm not selling any adapters by themselves as I need all the plugs I've got for people who will be buying full units from me.

TPS isn't an issue, you can use the wide range or narrow range TPS, or just use MAPdot for accel enrichment if you don't want to use a TPS....

IAC isn't hard either... the info for that is in the FAQ and in various other places.

So are you selling units then?
I thought I saw in another thread that you weren't making the whole units, just the plugs?

If you are selling complete units, be it with an adapter or not (I think I can handle that) then I might just want to buy a whole unit from you, all I need is a price. I want to do this very soon, like perhaps before the Deals Gap Rally!!!!

 

Sorry, but what adapter are you talking about..? The plug for the harness?

And Ken, I'm reading through that website, and you have me wanting to take the plunge.. looking forward to learning how to solder well, but I remain afraid of being stuck with a dead unit if I screw up. You seem to be very helpful to other forum members if something goes wrong, so that eases my spirits. Thanks for your help.

 

I encourage people to do it themselves as there's no better way to learn... the adapter is a db37->stock S4/S5 adapter that I include with my v3 units.

 

I'll be selling units as soon as I get:

1) more dead ecu's
2) all my daughtercards installed..

#2 will be done this week... I don't know when I'll have #1 done as it's kinda dependent on other forum members.

 

um... if you send me one, i garountee ill send you my ecu.

 

No, not MS II, you need MS I for a rotary.

 

I thought I read in your other thread that you were just building plug'n play units for s4's? Or are your units going to be plug'n play for s5 TII's as well? If thats the case I may just wait for that to work out.. my guess is you need a mule to test on in order to load up a basemap before you send out the unit and call it plug'n play.

Anyway, if I can get to my local junkyard I'll try to dig up some dead ECU's for you.

 

I was reading through the FAQ and you said that your re-writing the code for MS II.. any idea when that will be operable on the rotary?

 

depends mainly on when I can find someone to mass-build the megasquirts for me... I have no time to code when I spend so much time building megasquirts.

my plug 'n play kits for S5's won't run the OMP... you'll have to premix, but they'll be plug 'n play other than that.

And yes eagle7 thanks, you can't use the MSII on the rotary YET, I missed the msII comment that djmtsu made.

Tofuball's car is a not-quite-stock S5, most likely it'll suffice for a base map since he didn't change the ports or anything major like that. If anything his map will be a bit rich compared to what you'd need stock.

 

That makes sense. Your services are in high demand.

I forgot about the damn electric OMP.. I'm used to my old S4 NA. That stepper motor would be a bitch to emulate, wouldn't it?

I guess I can deal with premixing for the advantages of MS.. a small price to pay =)

 

Another question.. is anyone here using the relay board? Seems like it might be a nice convenience.

 

It's only really necessary on FB's since most of them were not fuel injected.

FC's have most of what you need there already, so the relay boards aren't really necessary.
