Racepak module for Megasquirt
 

http://www.racepak.com/images/buttons/bar_logo.jpg

A while back I got the guys at Racepak and DIY autotune together to create an EFI interface module for the MSI & MSII. They have worked their magic, it's done and available now. Fully compatible with DIY's Megasquirt PnP & DIYPnP.

This $375 module allows the following data to be displayed and logged in your G2X, G2X Pro, IQ3, UDX V300, V300SD, V500. Two simple commands load data into RacePak software, no need to manually enter and calibrate each channel. Yes, this also means you can display all that data on your onboard video using Racepak's free video integration software. Cool!

We're excited about this as it brings a very high level of functionality at prices that are club racer friendly. There are already EFI modules for AEM and many other ECU's. We will be carrying the full line and have the web pages for Racepak built in the next week or so.

MS I:

• Engine RPM
• Wat Temp
• IAT
• MAP
• Injector pulse width
• TPS
• Voltage - (any channel)
• AFR
• O2 correction

MS II:

• Engine RPM
• Wat Temp
• IAT
• MAP
• Injector pulse width
• TPS
• Voltage - (any channel)
• AFR 1
• AFR 2
• O2 correction
• Knock
• Knock Correction
• Ignition Timing

so $375 for the sub-pack...how much for the display?

Displays start at around $625 for an IQ3. Shoot me an email with an outline of what you need and I'll make some suggestions.
I can set up a package deal including shipping.

Wow. Great work, Emilio!

I took a quick look at the racepak website and didn't readily find the info: do you know what the GPS sampling rate is on the DAQ device? Suitable for autocross?

20hz
The G2X is perfect for autocross.

Fuck that is nice. Good thing I'm focussing on the MaX5 for now or I would've bought one.

Thanks Emilio, but I don't know if I can stomach bleeding out any more money on this car for a while. I'm going to whore the "used" market.

Holy crap. Very spiffy; I'm glad to see there was progress made.

I thought the product was going to have to run over CAN, so it was going to be limited to MS2+. Pretty neat that/if it runs on MS1 as well.

Kind of digging this ancient thread up, but any reason this module wouldn't work on a brain-built MS2? (previously MS1)?

No.

How about ms3.

We usually have the efi modules for MS1, MS2 and AEM in stock.

I haven't asked Tim and the guys to make a module for MS3 yet. My gut feeling is MS3 isn't fully mature yet.

The MS3 just changed the serial protocol in the latest alpha, so it is definitely not compatible.

Works with MS3 release firmware and alpha 11. I'll try alpha 13 later.

Want!@#!@$#@$@#!@

Has anybody tried using the Racepak dash with more recent MS3 firmware? Is it confirmed non-functional?

Anything past alpha 11 uses a different serial protocol and won't work.

Our enduro car, "Crusher" will be running and IQ3 and Smartwire power control system with MS3. We'll be using some of the ECU data fed into the IQ3 to display instantaneous and average fuel used per distance and per time increment.

We'll certainly share our experiences here once it's up and running.

I'll try next time I have a MS3 on the test bench. I have the G2X and display wired to the bench as seen in the video I posted.

My G2X, it is dead. :cry:

Racepak has been very responsive both on their forums and over phone with fixing hardware problems with the IQ3 I bought used. Only cost to me was shipping.

I'm a little concerned about mine. I sent 3 emails in early August and tried to get on the forum back in July. No emails were replied to and no admittance to the forum. I finally called for the 5th time last week and got an RMA # but had to pay the $100 expediting fee to get it back in 2-weeks because they ignored me for one month. I'm not exactly thrilled so far. I'd be temped to get an AIMdash before I bought another Racepak item.

Can the IQ3 compute fuel usage based on PW, injector size and fuel pressure?

Also why does all the cool shit cost as much as I paid for my car?

You have to setup your own channel and create the maths. That's exactly what were doing for the enduro car. Very precise fuel usage data.

Was there any update to this, or is alpha 1.11 the latest release that will work with the Racepack modules?

Currently is compatible through alpha 11 (and I guess 12 too, I didn't check that one). Not compatible with alpha 13 with the serial changes. Compatibility should be regained in the future.

Update:

Alpha 1.11 running VVT, talking to IQ3 with VNET sensors and Smartwire. I lost track but I think we have something like 50 channels we can monitor on the laptop and 32 we can actively datalog at any time.

Any news on the MS3's latest firmware?

Good bump of a year old thread.

I asked Emilio on m.net and he said it's good for the latest MS3 software.

Guys -- Please email RacePak and put a bug in their ear. I asked them (like a year ago) if they would develop a module to interface with MS3 over CAN. That would ensure complete compatibility with any MS2 or MS3 regardless of firmware version. While they were receptive, I don't know if anything actually came from it. I suspect that if they felt demand, they would offer the support.

I honestly do not know if the RacePak module for MS2 is compatible with current MS3 firmware. It was compatible with older firmware versions, but we made some changes in serial protocols at some point, and that broke compatibility. I have not checked in a while. If I can find some time, I can test with our G2X.

Not true, if the outpc structure changes, compatibility is broken.

Valid, but we have several new products in the pipeline that operate over current CAN protocols, so they're here to stay. There have also been developments with running 2 different CAN protocols simultaneously.

Dmitris and Ben, let me know what we need that we don't already have. I can get it pushed through sooner than anyone here. As mentioned above, we're on MS3 alpha 1.11 and I think maybe 1.14, running fine. If there are distinct benefits from doing a CAN protocol MS interface module, then let's do it.

What alpha are you guys on for MS3 now?

As you know, there is not an MS3 specific serial > racepak interface module. It just happened that the MS2 module would work with the old style MS3 serial comms, and while it would work, it would only work to the extent that it would display hte channels that happen to be in common between MS2 and MS3. None of the many, new channels that exist in MS3 that do not exist in MS2 are supported by the MS2 adapter.

I think the best way to fix this is to set up the interface over CAN, so all data channels would be supported, no matter which processor (MS2 or MS3) and which firmware version is being used.

Current release firmware version for MS3 is 1.1.2
http://www.msextra.com/doc/ms3/files...ease-1.1.2.zip

There have been a lot of refinements and extra features added. You should upgrade, but I'm pretty sure it will break comms with your RacePak dash.

OK, request is in for MS CAN interface module. I'll keep this thread updated as new info becomes available.

That IQ3 brought a tear to my eye. So sweet.

It would hard to go back to having no data now that I am accustomed to having everything on the dash.

Well my IQ3 logger is on its way with oil temp and oil pressure sensors. Rest I am depending on the information out of the megasquirt. Let us know if the interface ends up working with MS3 and I will order the interface right away!

Order it from who?

We're a stocking Racepak dealer and the folks chiefly responsible for making the MS compatibility happen.

I cannot imagine racing a Miata without an IQ3 now.

Hey, my G2X is junior baller.

Subtle "bauce motherfucker" post.

The IQ3 I got from someone I know who bought one and didn't use it. The interface I will order from you guys! Well once I know it will work with MS3.
Who should I bug at RacePak?

data link 4.1.1 is out. If you are a Racepak user, you want this!

Racepak Data Systems - Professional Motorsports Data Acquisition Systems

Any update on the vnet interface compatibility with the latest MS3 firmware?

Thanks.

Nothing to update. Been working just fine with MS1, 2, 3X and pro for a few years.
