Tuning what?

Build time.

What's this, you ask?

A fuel and spark computer! (I'll only be running fuel off of it for now, as spark is a little on the tricky side for me to adapt to the computer currently in my car)

What does this mean?

A Saturn near you is going to gain somewhere near 30whp. :p

[D Money]

I didn't want to be the first to say it but 30whp? Bro, 30whp is alot. What are your plans as far as dyno numbers are concerned?

[xEJ20x]

So what system are you using? MegaSquirt?

[99SL2_Modder]

I didn't want to be the first to say it but 30whp? What are your plans as far as dyno numbers are concerned?

31whp on the dyno is what I'm shooting for. 30hp from tuning + 1hp that comes with the car stock.

Yeah, only 30. It's n/a and running filthy rich. Actually, for subie owners, it's running in the sweet spot, but for regular n/a car owners, it's spewing raw gas.

So what system are you using? MegaSquirt?

Yes. MS1v3 w/ MSnS-e

30whp is alot, I will say it again, especially for NA. What other mods are you adding to gain 30whp, or do you feel you can gain 30whp just from tuning?

[99SL2_Modder]

With all the other mods I have already on the car. I believe tuning gained almost 30whp from actual dyno runs. They run extraordinarily rich from factory, and once modded, start running around 10.5-11:1 afr's, when they should be running near 13.5:1.

30whp is a lot, yes, I'm actually more hoping for like 10whp, but the mods I've already done to the car got a few extra ponies out of it as well.

If it makes you feel better, I can say 30bhp, which is much more realistic.

Some progress:

Not too horrible for being 8 years rusty. This is actually really relaxing. I missed doing this stuff.

Whatcha think?

Same here...I also have a MS on the way. I'm excited to see what kind of difference it makes.

Prebuilt or a kit? My buddy has one with less mods than me and I can barely see his tails if we race.

I'm a noob to this, so it should be "interesting" when I tune.

I have a base map from when I was fiddling with it before, but it's gonna take awhile for me to get it right. Of course, my base map won't work with your car, so...

450??? Damn man, you got ripped, no offense...

That makes the power circuit, serial com circuit and the clock circuit. It's about halfway done. Stopping for the night, I think.

Yes, that last pic looks sloppy. This solder has a TON of flux in it. That's not solder you see, it's flux.

30 whp in a FWD car, that's madness. Madness I say!

[adamkob32]

30 whp with nothing more then a megasquirt in a saturn. Clint I think you have gone over the edge this time. Be prepared to be disappointed, all I gotta say.

Nice to see some progress finally.

--Adam
I don't expect to get 30whp from just the megasquirt, but I don't feel that I've gotten the full potential from all of the modifications that I've done, so the MS should bring it out to the full potential, and THAT'S really where I'm getting my 30whp.

Yeah, my progress takes breaks, but what I do the mods, they go in groups. The manual swap should be completed in a month or so, depending...

Ahhh I see your talking 30 over stock with all modification. I thought you meant 30 over what you have right now. All in all though that is tons and tons to pick up on a Saturn with boltons and fuel. I just don't really see it.

You don't see 130ish whp?

I do. Easily. Someone hit it with the exact same setup...well, except they had the good head, not the POS I have.

(talking auto, not manual too)

[adamkob32]

Yea I see 130whp easy. That's not exactly a 30 whp gain.

[99SL2_Modder]

Yea I see 130whp easy. That's not exactly a 30 whp gain.

How isn't it? IIRC, they dyno'd out at roughly 100whp, usually slightly under.

Again, auto, not manual.

[99SL2_Modder]

What do you mean? On a properly tuned car it will throw no codes. And if it does, I'm planning on a 4pdts to flip between the 2 controllers, so I could swap it back to the PCM to have it control it for a week or something.

Hahah just busting on ya', I love that thing whatever it is. I love living in Schuylkill County and still not having emissions. I think anyway. I might rather have it and get some of these damn bombs off of the road though.

clint... from what i saw in the pics your solder is OK... but it needs a cleaning BAD get an acid brush and some alcohol on that SOB! good luck with the MS i've heard people having great results with them.

You see it's very likely that my car and it's overly engineered ecu will throw a fit for not being in control.

[99SL2_Modder]

This solder has so much damn flux on it.

Yeah, I was planning on running out when I was done and grabbing some 90% rubbing alchy, cause all I have is 70% and that doesn't work well. I could use acetone too, but I'd rather not.

You see it's very likely that my car and it's overly engineered ecu will throw a fit for not being in control.

Your computer doesn't know when it's in control of the injectors or not. As long as it doesn't run too lean or too rich, it won't know the difference.

[KrautFed20V]

i can bag you some 100% isopropyl if you need some to clean your board... and if you feel like missing the board for a day i can vapor degrease and Conformal coat it for you. it's what i do day in day out... so i'm used to looking at stuff like that.

[Raven18940]

Your computer doesn't know when it's in control of the injectors or not. As long as it doesn't run too lean or too rich, it won't know the difference.
Again, overly active ecu and it'll know...somehow. My ecu constantly fiddles with the injector timings and when it can't fiddle it'll have a fit.

Conformal coat? That like a corrosion preventative? Technically, I can be a day without the board. But like I'm saying, I've gotta get a few more things soldered in, but it should be done by tomorrow. (hopefully will have the few missing pieces by then)

Pretty much done:

Gotta make a few jumps (D1, D2, XG1 to XG2, OPTOIN to TACHSELECT, TSEL to OPTOOUT, and I think that was it)

(Yes, I know the part by the proto area looks like crap, but it's all flux. You can't see it until the flash hits it. This wire had a TON of flux in it.)

Those tight pin spaces with the pots and the like were a pain in the balls. Need a narrow tip iron next time...

maybe he means that his car currently dyno's 1whp and after he does this computer chip he'll dyno 31whp... :screwy:

31whp on the dyno is what I'm shooting for. 30hp from tuning + 1hp that comes with the car stock.

[igo4bmx]

I would honestly find a way to control timing while on the dyno.

[KrautFed20V]

conformal coat as in corrosion/ ESD / vibration dampening layer of polymer that protects the board, i would just leave coating off anything that needs to be soldered/ jumped ect.

[SoStock92]

I've built 2 megasquirt v3 with MSnS-E with 6 COP spark control for bmws. If you need any help - holler.

http://e34.digital7.com/MegaSquirt/jjdickmms1.jpg

Dont conformal coat it you will have a hell of a time accessing components if they fail. Just use 99% isopropyl and a tooth brush. I have washed mine with dish soap and water before too, as long as you wait for it to dry you'll be fine. You have a bunch of bad solder joint on that underside. consider reheating that area in the upper right. You want the solder pad to be conical and shiny/almost chrome looking, not grey and jaggy.

That's some hot **** man. I'm using the MSnS-e also, but without the daughterboard. The program works fine without all the other stuff.

But no, if he uses the right conformal, you can solder through it. THat actually might be the krylon stuff...I'll have to check again.

And like I said, that upper right isn't bad. They're all conical. The flux in this wire is in disgustingly large amounts.

I would honestly find a way to control timing while on the dyno.
My car will hate me controlling timing. At the moment, there's no way to properly control my timing without swapping ignition modules and throwing a bunch of codes. It's easy enough to swap back and forth for emissions and the like, but at the moment, I don't have the time to fab up mounts and extend the harness to be able to dual mount. Or the money, no less.

[KrautFed20V]

conformal coating i am talking about is Arethane co. Urelane 5750 is removed easily with a q-tip and alcohol OR you can burn it off with a soldering iron (i spray not dip or vacuum deposit) just dont' breathe the fumes if you do that. so just let me know clint.

Rob

ps if you haven't already... try tinning (thin solder coat) the parts before you put them in the board you will have much better solder connections (less grainy appearance) and try not to hit them too many times... it makes the intermetallic layer weak when you do that.

I gave it a quick toothbrush scrub in acetone and 70%, but it looks like it could use something a little better.

[99SL2_Modder]

Been thinkin about this again. Your car is new enough that it has the craptastic GM computer, correct? Not a true Saab? So, then, you shouldn't have an emissions issue with just fuel. Your computer shouldn't even detect a problem.

Here's my experience on my OBDI BMW -


I have the injectors hooked up and MS setup for 30# injectors (for sale btw, the 315cc injectors), VR sensor, dedicated GM coolant sensor, dedicated GM open element IAT sensor, TPS signal tapped, LC-1 Wideband input, no idle control.

Of course i get CEL - injector valve fault, since Motronic isn't seeing the injectors. But, that's not the worst of it. When the car comes out of warmup mode (the Motronic, not the MS) the idle goes hunting. The thing idles strong as **** until that Motronic comes out of warm up mode, then it seems like it messes with the IAC valve but since its not controlling fuel, it just moves the IAC around and ****. So, if you go and try and do fuel control, you need IAC control... that's been my experience.

See, I've never really run into a GM car that senses the injectors. They don't seem to see them. We've not had any CEL's on OBDI or OBDII (saturns). However, I'm unsure of all other GM's, but IIRC, there's no injector readings on any pre-2k's because it costs too much and we all know GM is cheap.
