How much was the kit?

How much was the kit?

$639.99 plus shipping. If you have swapped to an LA3 and installed the IAT sensor already you can get the Turbocoupe Kit for $599.99. The SVO kit comes with an IAT sensor, wiring and bung for installation into the intake tract of the SVO. He'll also knock off $20 if you return an OEM ECU. He uses the ECU cases to house the adapter board so that it will fit right back behind the kick panel.

I can't emphasize enough how nice this kit is and once we figure out what my issues have been with the instructions it should be plug and play for all that follow.

Edit;
Holy crap! I didn't know you just retired. Congratulations! I've been retired since June of '04 and am loving it. The business group I work for within CACI is headquartered in Norfolk, just a stones throw from you. If you ever need work let me know and I'll point you toward my boss up there.

Thanks man. I will keep you in mind if need be.
I pesently work for a company called CB Richard Ellis. We maintain the server farm utilities for the Navy Marine Corps Internet (no I can't fix the computer problems, I just make the servers comfy and ensure they have power)

Now, back to your regularly scheduled program: "Mega-Squirt"

You need to let us know how this MS setup works out for ya. i'm seriously looking at it and ditching the MAf conversion i have.

the MS you bought looks like a great unit.

tateg,

The cranking pulse width has to be just about spot-on perfect for the car to start. If your fuel pump is turning on, and you get an RPM in your datalogs, and the car was fine before, try giving it about 25% throttle. I bet it will start.

I'll try that. The PW reading while cranking is 5ms and the RPMs read around 100 while turning over. I'm pretty certain it's right on the edge of cranking since it was tested in a TC before shipping. The more I think about it the more I think I forgot to plug up the MAP sensor; or maybe it's wishful thinking. Considering the convoluted and tight route I took with vacuum line it may be constricted too resulting in the same thing as leaving it unplugged.

"Bolt-in" ready to use Megasqirt??

Saw this over at TurboFord. Neat set-up. Anybody tried this?

Oops - sorry. Posted this before I read the whole thread. My Bad.

I spoke with Nathan last night and asked about the PW. He said that after he test drove it he changed the injector size from 36lbs to match my 52lb injectors but he forgot to change the PW. He told me to lower it from the 5.1 the 36lbers need to around 2-3 and it should crank up. He also said that I should remove the SPOUT if I still have issues to see if it starts then.

I got a base tune for a stock 2.3 but mine is fairly modified so it will take a little adjustment to get it right. Anyway, we shall see in a couple of days.

So if you get that will you still need to do any rewiring on the car or is it honestly a plug and play setup?

[yeahloh]

that sounds great! if you get yours up and runing, i'll order one tomorrow

Here's an pdate:

Spent about 30 minutes with it yesterday and got it running. The auto hobby shop on the navy base where I work on my car has been closing early for the holidays so I only had 30 minutes. So keep in mind that all together I've spent only about 2 total hours tinkering and that includes the installation time as well.

Anyway, I got it running but it's still needs some adjustments and it's not reading my O2 sensor. There are two sets of wires coming out of the adapter board that just plug in. One didn't have screws to hold the plug firmly in the socket so it came out sometime during the installation. With this plug out the ECU wasn't getting any AIT sensor or O2 sensor data. I let Nathan know about this issue so he could fix it for the future. I got it sort of reseated as best I could without cracking the case (there's a sticker that says warranty void if opened). This allowed the AIT sensor data to the ECU but it still wasn't getting the O2 sensor data. I've got Nathan's assurances that I won't void my warranty if I open the case and secure the plug. I could have fixed this in the 30 minutes I had yesterday but I wanted to email Nathan first.

So anyway, I got everything running as best I could without any O2 sensor data. Actually considering it was essentially in some kind of failsafe mode (pig rich) without an O2 sensor it ran pretty good.

Thanks sar4497; the starting issue does seem to be cranking PW related (I'm running the 52lb injectors and the PW from Nathan was set up for 36lbers) and it did start right up when I unplugged my SPOUT. I had adjusted my PW over the weekend so all I had to do was load the tune into the ECU to modify the starting PW's.

Keep in mind that my car is no where near stock. The closer to stock your car is the quicker you will be up and running. And I think that 120 minutes is pretty fast for a modified car as well.

You will *HAVE* to install an IAT sensor but the wiring for that is separate from your harness. Everything else is just a plug-in setup in place of your original ECU. And you will want to remove your VAM and everything in front of your turbo but the filter. I guess you could leave it all in place and just unplug the VAM until you get it tuned to where you want it. And you will have add a vacuum line (supplied) to give the MAP sensor what it needs to monitor air flow.

What size injectors are you running? What are your PW values for starting if you don't mind me asking?

So with this setup you are eliminating the VAM completely? Is it just a straight shot from the filter to the turbo then?

Megasquirt is speed density. no vam, but you need to run a signal line to the MAP sensor in the MS unit.
