    test fired 454 with supercharger

    in Non Tech Board

    Posted

    Finally got my 454 with the B&M 250 test fired. I just used a holley 600 and large cap HEI for the startup to break in the cam. It really sound good.

     

    Now I am making the switch over to megasquirt with throttle body injection and EDIS ignition setup. I have all the parts in hand and will hopefully have a video in a few weeks running EFI and distributorless.

     

    I did have a little steam come out of the left side after the second run, I think it might be the intake gasket near number 1, I had some issues with that. Probably have to pull that down and check it out while I'm putting together the wiring harness for the megasquirt.

    back from vacation and first MS failure story

    in MegaSquirt

    Okay, this is the first time one of my cars running megasquirt has developed an EFI system problem. It is my Talon and it hasn't been idling correctly and using too much gas. Turns out the IAT sensor broke. It worked for around 12K miles. I put in a new one and all is good. Megatune showed a constant -40 degrees.

    What EFI pump for 60 gal/hr at 50psi

    Have you tried to run two pumps in parallel before? Another thing I was contemplating was running two of the Master/Airtex E2000 pumps. They are $75 are flow 30-40 gallons per hour each according to some info I dug up. Even on the low end they would give me what I need. The A1000 pump is $300 so that could save me quite a bit. Right now it would be easy for me to run two hard lines up to my firewall, then Y into a single 1/2 inch line right at my fuel rail.

    Need help selecting Megasquirt model

    I Believe Ultra Megasquirt will have a sequential option. But who knows when it will really hit the market.

     

    The high resolution for big injectors is certainly worth it, I can attest after running 850cc injectors on my 2.0l Talon. I do not have the high resolution and idle surges most of the time.

    Here is a noise/reset update for you guys

    in MegaSquirt

    Posted

    Out of the 5 megasquirt installs we did last year there was one that never functioned correctly (Chris's car), some of you probably remember the description.

     

    Resets all the time in the beginning, tried several noise filters at alternator, by MS, by coil, etc. Tried not hooking up alternator. All the usual stuff that everyone sees and tries with reset problems. In the end it seemed like moving the MS box helped some.

     

    Well, here is what my friend (Mike) found yesterday....

     

    Mike took back the suspect MS box and decided to check it for cracked solder joints, because the history of the resets shows that they come and go with no reason. Sometimes Chris can drive the car for months with no problem (it is his daily driver), other times it resets several times in one day.

     

    When Mike popped open the case last night he found the processor was not plugged into the socket, one whole side was hanging out and just barely making contact enough to work sometimes. We are sure that the processor has been in this state every since the unit was built (built by Mike, not DIY or anyone like that). Anyway we are waiting for the updates now, but it may take several months to verify no resets every happen again. If they do, the next thing we are going to do is re-flow all solder joints, because it was soldered by him and was his first solder job.

     

    The processor not being seated in the socket correctly seems to be the cause of this one, you guys also be careful that one or two pins don't bend under the processor when it is seated, I have seen that before.

     

    At this time the only conclusion I can draw is that the other 4 units I built work fine to this day, I have had professional instruction with soldering and have been doing it for 10 years in my various hobbies. The one unit that Mike assembled is suffering reset problems. I guess the moral of the story is to have DIY or someone else build your MS unit if you are not sure you can do a good job soldering and assembling the other parts of the unit, seating the processor :)

     

    These resetting problems are so frustrating that it is not worth saving the money to assemble yourself.

    Just a few ms. questions

    I know i'm gonna get ragged on

     

    bumping after 4 hours, yeah you should probably re-evaluate using megasquirt. I would say you don't have the patience for it.

     

    Start training yourself to accept that it might take days, weeks or possibly months to get megasquirt installed and working depending on your level of knowledge and the luck you have with MS.

    Well, that was $200 Shot in the Butt...(longish)

    Install an in dash radio and see if it also suffers from noise. Might give you something cheaper than a scope to use for troubleshooting, and most likely your noise is in the audible range. Just something easy. Otherwise sell the MS boxes to someone else and use the money to buy a different standalone. I would borrow an ECU from someone else, like an SDS if its possible and make sure it will work on the car.

    I will be out for the Holidays

    Just wanted to let you guys know I will be out from Dec 15th to Jan 8th. So if you don't get replies you won't think I'm stuck up or something :mrgreen:

     

    I should pop in once in a while, but I'm not sure.

     

    Happy Holidays to everyone and I'll see you next year.

    I'm sorry guys for the unsystematic approach at times

     

    If his comment was a sarcastic one it was inappropriate. We have all been overwhelmed and asked a lot of questions at some. We always need to remember what it was like when we started and use a nicer approach with new people. That keeps everyone interested in the hobby and its all about having fun. Good luck with the rest of your install. I have made sarcastic comments also, I am working on that.

    Anyone into martial arts?

    I went to a karate school 10 years ago for a while. Now I am studying in the area of Jeet Kune Do with my son. We train 5 nights a week and usually more. It is a lot of fun and anyone familiar with this will know that it can include pieces of every martial art and fighting type. Right now we are concentrating on kung fu, chin na, kickboxing, and some kenpo. I am debating on buying the definitive Dan Inosanto collection on DVD to keep us busy for the next couple years. Good to see some other people also share interests in the martial arts.

    I got my MS 1 V 3.0 today!!

    I'll second the wideband computer and sensor.

     

    With it I was able to install MSnS_Extra in the talon and then tune in 30 minutes of driving covering all load points in the VE map.

     

    I am still running that same tune 11K miles later and have been running at 18psi. AFR's are steady where I want them and I couldn't even imagine running 18psi without a wideband or pyrometer or local shop tuning.

    wont advance

    also, just because I never know for sure what code version people might use, there was the old error that required -9 to be entered instead of -10 (for fixed angle to cause the switch back to the table for spark values). But that was in the older MSnS_Extra versions like 021u or something.
