MegaSquirt system on stockers?
 

Just wondering if anyone is running or has tried to run any of the MS systems on their stockers or other cars and their experiences tuning, driving and bracket racing. I'm finally needing to upgrade my OEM system and I'm to cheap to go buy one of the BIG 3(E,F,&H) systems.

S10....I sent this via private message because well, its a secret................ssssssssssshhhhhhhhhhhhhhhhh h

But seriously, if you are already and EFI guy then youre probably in better shape than we were, my idea of Fuel Injection involves mechanical pumps and pills.

We tried to find who knew (and manufactured the best kits for other "Evil Projects" and needed someone to teach and show us what we didnt know)

Jerry and his crew Matt Cramer, Russ Patrick and the whole crew all (pretty well know for building some odd efi stuff) as well as their ties to and with James in the Uk, James Cortina I think is his handle one of the head coders of the project) to write the custom code for us that we needed for the Hemi trigger and cam wheel.....They did it in stellar fashion. We sent them our Challenger SRT8 and the DP Manifold and in 3 days they had installed , wired, written the code, tested and had it running........on an SRT8 Challenger test mule.

They are a joy to work with and well, fuel issues are one thing were not having. I have never ever heard from them NO, I have heard, Sure....no problem, and then they make it happen so fast its crazy....

They are one of the companies, that sells and SUPPORTS their kits, from assembly to tuning....GREAT guys to work with and an impressive facility.

They are the people to talk to in my opinion, I would call them even if I was going to use another system.

When I told them what I wanted and what I needed, and if they could do it, I didnt get "Yeah" and then a BS of failed dates on my nutso schedule I got, give us a few days to talk to everyone needed to make this happen right and well get back to you. The answer was yes, but it was a thought through YES.......not a Yeah Ill sell you one and leave you to hang like some of the other vendors of systems.

AND there are a LOT of guys in the MS community that will help and want to see your success. Since its a "community source" type project your sucess reflects on them.

If I can be of any help drop me a line or give me a call

Cheers

I think the Megasquirt was originally developed by Bruce Bowling and Al
Grippo they were a couple of the patriarchs of the old diy-efi.org group a collaboration of programmers and electrical engineers who I think started out reverse engineering GM ecm’s back in the mid or early 90’s. Fun bunch of Brains that started it all to put EFI on their automotive projects. I think a couple of the guys were into turbo charging grenades. They would get a junkyard engine throw crazy amounts of boost at it and see literally how may seconds it would last on the dyno.
I have not visited the web site or been on the mailing list for many years but I do recall on the site for the 68332 Al did a page with all the control algorithms it was interesting stuff.

Re: MegaSquirt system on stockers?
 

Being a programmer the idea it can do ANYTHING I want it to, thats attractive....I was joking with the Guys down at DIYAutoTune and I said I want the ECU to be able to trigger my auto garage door openers when the CO gets above a particular reading they said no problem (it was a joke on my part) but they were serious...Our system has some "trick" items that well, I didnt even know were possible let alone easy.........

Very cool system in my opinion, just buy a prebuilt, the one thing about the "open source" projects is there is a TON of documentation out there on just about every kind of install and engine combo imaginable.

Picking the RIGHT MS system is a biggie and the right support items.....there are a TON of variations of both the I and II and soon the III the I and II are NHRA approved...I dont think the Microsquirt is, it may be though.

Re: MegaSquirt system on stockers?
 

Thanks Drooze for the inpute. Your secret is safe with me. I was looking on that site yesterday and I came across the Challenger and said to myself"I wonder if that is that Drooze guy's car." Well I guess we know who that sponser was you were talking about. Sorry for doubting BTW. What I was mainly concerned with was the limits of the MS as in RPM, Odd vs. Even fire 4.3s and so on. Was looking for a # for Tech Support or Tech sails. I hate doing everything online and getting hung up on something hard to me and yet easy to someone else. I end up having way more problems getting software installed on my laptop than the tuning itself. I was also wondering about the MAF. I would like to try a AN,SD, and a MAF setup for speed and that other one. You know, the thing that helps you in bracket racing. I believe it starts with a C. Anyway, Thanks again. And yes it sucks being #1qualifier at a race in 08 and being bottom of the sheet in 2010 moreover the fact I was on the tree all weekend. I just can't seem to put me and that truck on the same page. YET

Why did you change your mind George?

Did you get your files OK?

Ed

Re: MegaSquirt system on stockers?
 

Yes Ed thanks. Not changing mind but exercising options. The price for that cutover with the software I would need to purchase was a little higher than expected. I may have also found what was my problem for the SNs. I called you yesterday, but you were very busy. I will call later. I promise I won't honk the horn OK.LOL

Re: MegaSquirt system on stockers?
 

I pm'd my cel number to you.

Re: MegaSquirt system on stockers?
 

Jerry from DIYAutoTune.com here, I'll be glad to share our number, we just don't have it posted up on the site as I'd have to hire twice the tech support staff and raise prices on everything to pay for it ;). Email is generally more efficient for most questions (websales@diyautotune.com) and the three guys manning the email and phones are quick to respond M-F 8-5 EST. That said there's time when a phone call just works better and we understand that too. 678-261-8789

The tech guys are Matt, Russ, and Ben, and I'm sure one or more of them will drop by this thread soon to say hey.

Re: MegaSquirt system on stockers?
 

Matt from tech support here.

The highest RPM I've seen the MegaSquirt used at was around 16,000. The only time I've seen one "run out of RPM" has been more along the lines of sensor compatibility issues.

Even fire is a lot easier to handle but the MS2/Extra code will run odd fire motors too.

GM MAFs are not all that easy to use with the MS - I know, kind of surprising given that GM sensors are usually the default. Support for frequency based MAFs is planned for MS3 but not there yet. I have seen some people use frequency to voltage converters to make them work but this is nowhere near easy and very much a use at your own risk idea.

Ford MAFs are a bit easier. However, most of the knowledge in the user community revolves around speed density and alpha-N.

Re: MegaSquirt system on stockers?
 

Well I picked the phone up to call and ask you this Matt, BUT I thought for a second (i can do that from time to time before I act on impulse alone :)

And I thought well since I dont know, and well maybe there are other who dont know....so we can all learn.

So 2 questions to 2 groups

1) S10....Why do you want to run a MAF ? For drag racing it seem to me being (but having a base understanding) to be an extra item to worry about in the chain that isnt really neccesary ? But seeming as your sharp, you must have a reason or feel there is a reason.

2)Anyone else including Matt, what are the Advantages/Disadvantages of using this over Alpha-N or Speed Density or Hybrid ? Why would someone WANT to run it and have to go through all the extras surroinding it ?

I thought (maybe incorrectly) that MAF was "old" even on new cars.....or am I just stuck on a couple types that dont implement it .... the SRT8 dosent have it does it...lol....

Cheers

Chris

Re: MegaSquirt system on stockers?
 

Well since you have helped me so much I have no problem answering those questions. First let me start by saying this is very much a per application deal. I do lean on guys like Mr. Ed Wright with Fastchips and Geoff Skinner with Engine Power Systems alot when it comes to using stock ECMs. Mr. Wright did my first tunes on my computer by mail order and Geoff was able to sell me the ability to do my own programs so I could make moves at the track. When it comes to engines that at their max RPM could never outflow a MAF why not at least try. With the factory cold air intake and ducting a MAF shouldn't hurt, but how will you know unless you try. Now I have never ran any programs but MAF; however I could pull my race motor and install a 4.3 bone stock from the factory and it will not only run well but great(as for a stock engine). The MAF is the answer. If you have most of the maps built to use Air/Fuel ratio via the MAF and calculated flow of the injectors & temp, what is behind it shouldn't matter much. You can set up a MAF program and use that to build AN or SD program by datalogging your sensor reading in running situations. Now I may be oversimplifying this but that is my thought process.

P.S.I can't spell worth a crap and I don't have spellcheck so forgive any misspelled words.

Thanks also to Jerry, Matt, Russ, and Ben and y'all will be hearing from me soon.

Re: MegaSquirt system on stockers?
 

I must be so happy today and on cloud 9 because of my bearing clearances and Ive checked em twice and plastigauged them and all 100% the same measurments and PERFECT like .0035 perfect (and thats what I wanted) and all so close I was scared and checked em again.

I didnt pay attention, well I read it but it didnt "compute" that you were using the stock ECU, makes a world of difference .....

Derrrrrhuuhhh......

Sorry didnt read the MAF either read it as MAP ?

Deerrrrrhhhhhhuuhhhhh.....

I get it good point, it seemed like an awful long extra way to go on an aftermarket ECU......

But your not and I see every one of your points 100%.......Now......see good for me to ask than be confused....

Re: MegaSquirt system on stockers?
 

You have to be kidding...are you really using Plastigage on a high dollar engine?
The proper way is to determine bearing clearance would be to measure the OD of the journal diameter of the shaft and subtract from that the ID of the installed bearing insert, the difference being the clearance. Spend the money on the right tools and it will save you a lot of money in the long run.

Re: MegaSquirt system on stockers?
 

Sheesh back off....I Did TWICE I have "the right tools" I use plastigauge as secondary across the journal. I DID it the right way TWICE, Did it once and took it apart for another reason. Did it AGAIN , and then put it "together" in mock up to check cam and ptv clearances, and since I was there I used plastigauge.....

Didnt hurt to "verify" and it did, spot on.

Can you spin the rotating assembly without the heads, effortlessly with a speed wrench?
