Another MS conversion, Progress, at last. Options

[VaccaRabite]

I agree with Mike. At this point you need a dyno and a guy with a lot of experience tuning EFI. Your cam is mild enough for CIS. I'm not sure how a light flywheel would effect this. I am confident you can tune this out.

I went out this morning and got a pressure gauge (3 FLAPS and finally to Vic Hubbard Performance).

The gauge reads 24, Haynes says 34. I'm gonna guess that a 10 pound drop makes the pump essentially useless. And may have been contributing to the problems since MS went in.

Good thing I like the guys a Parts Heaven.

Mike, do you know where there is such a place in the Bay Area? I have not done a lot of tuning because there have been, hardware, noise and cold start issues since the installation. Now that those have been taken care of and the fuel issue will be solved shortly, I will spend some time tuning.

[JimN73]

I searched for dynotuning in the Bay Area and found one shop in Pacheco that says they tune MegaSquirt. Others tune 'other efi' systems and a whole lot of the sites are for shops that don't exist anymore.

Phone calls on Monday, after I get a new fuel pump.

Sounds like the same place.

BRG Racing is the place I used. I tuned my self but If I did it again, I would have them fool with it. The price is about the same.

Thanks, Mike, that's the place I found, too.

Glad to hear your making progress Jim, hopefully this will take care of it.

Mike, your project is the only successful Micro/MegaSquirt project that they've had. And one that didn't work. They'r going to do some research and may take the project. I'm not sure that's progress.

There are other dynotuners in the area, I have many calls to make.

[r_towle]

Sorry to hear you are struggling so hard with the system.

Good luck, but your fuel pressure is to low.

Just saying.

Try Sias Tuning. Vic Sias is a former SCCA National SoloII champ. He is a former Z car guy and I think autocrosses the snot out of a BMW these days.

[JimN73]

I know, Rich, thanks.

I bought the pump (rebuilt) less than a year ago with a one year warranty. I talked to Jeff at Parts Heaven on Saturday and they replaced the pump. The replacement jumped all the way to 27 psi and is really loud.

I went back to Parts Heaven today and explained to Spencer what was going on. Take another pump, he said. I did.

I won't get this on in til Friday. Wish me luck.

Redline sells a 'uiversal' pump for $71. anyone have any experience with it? Are there other options?

[Chris Pincetich]

Good luck Jim! (IMG:style_emoticons/default/beerchug.gif)

I would seriously contact Mario Velotta at www.thedubshop.net. Mario is the absolute best Megasquirt tuner I know of, bar none. If you e-mail him your .msq file, he can probably find the tuning issues and correct them. Either way, I would definitely call him and discuss your issues. Tell him Nate set you. . .

[Mike Bellis]

There is a dyno shop in hayward. They specialize in Haltech and ricer cars but they may be able to help too. I forget the name but they are located around Huntwood/Whipple area.

I am using a MSD 2225 pump. It's kind of loud, but not too bad. I have it mounted in the front trunk. I think it was about $100 from Summit.

I use the Ford F150/Crown Vic external pumps. They are cheap, reliable and deliver plenty of fuel. Just put a regulator on the return line and you are good to go.

Progress!!

In the last week or so Mark and I have made some changes: put in a new fuel pump and filter and straightened out a couple of fuel lines, a new ECU, and new trailing arm bushings.

I think the fuel issue and the ECU have cleared out the background issues and left the real problem clearly in view. Between 2000 and 3000 rpm it bucks. The PW and MAP bounce around a lot. I'm not sure which is the cause and which is the effect.

I have done a lot of reading and made many changes to the tune without ever changing the bucking. Here is the most recent tune and a short log showing the bucking and system changes.

Does anyone have any idea what might be causing this?

Sweet! logs! ill take a look. Is that the MSQ that was in use when the log was generated?

I have had the same pump on mine for 8 years now, works great and cant beat the price. It is a bit loud though.

I've sent Mario my files, not quite as current as I just posted, but pretty much the same. He's looking at them.

thanks, Nate.
