Now, it may cost you a Venti Starbucks and a slightly used TME...lol. J/K.

AMS has no problems tuning the XEDE. The only problem that you are going to run into is that Martin is apparently booked until July as far as tuning goes...

IMO you are trying to rush something that shouldn't be rushed. Installing a stroker and potentially a turbo kit and getting it all dialed in and tuned is going to take longer than the 3 weeks you have left to do it in.

I will leave the TME on for now, and try to get a "shelf map" from Shiv, if that is a reasonable way to do it!! I don't want to rush it, but then again, I dont want to flip burgers while everyone else is having fun either!!

Whatever you do, don't use the map that is in the car now to even drive around the block after you get the flash and put the scaled injectors in.

If you want, I can upload a map that I crippled and used until I could get to the dyno right after we installed new injectors in my car. You could load that until you get on the dyno. The car will be slow, but safe. Let me know.

Hey Noize!! Any openings for the Dyno4mance dyno? THats what I need! Oh yeah, thanks for the map to make the car drive. if there is an opening at the end of this month, I can just trailer the car to Andrews, and work from there!!!

Another question, if I cant drive with the Xede and ECU without the "scaling" of the injectors, I guess I cant break the car in before the Dyno, correct?

Someone correct me if I'm wrong, but shouldn't the maps within the stock ECU be adjusted to accurately reflect the injector size and additional displacement? I.e.: it needs to be reflashed before you can drive the car at all. Once you've got the flash, then leave the XEDE disconnected and drive around on wastegate boost only during your break-in period.

Great question. I hope someone has the answer to this one. I would disconnect the Xede to get the break in miles, or it will turn into something ugly!!

You definitely have to reflash it before starting the car with the new injectors in. After that, you could bypass the XEDE, but it would be a lot better to put a map in that has reduced timing instead. With the XEDE bypassed, this couldn't happen.

You can make the map easily enough yourself, Smoked. Zero out the boost and fueling maps so you run off wastegate and whatever fueling the flash is set at. Next, retard timing from 3000 rpm all the way to the top about -2.5 degrees. This will make the car a lot safer post injector install.

I still wouldn't get on it, but just drive it around to commute in until AMS can have a go at it.


About Dyno4mance, the days with Shiv are overbooked, sorry about that. You could schedule time in with Andrew, but if AMS is going to have the car anyway, I know they could take really good care of tuning you as well.

Thanks for the tips Noize, I appreciate that!!

You might want to post this question in either the general tuning or engine/drivetrain forums. Personally I still don't think it will be as simple as scaling for injectors and leaving the stock ECU maps alone. With a 2.3 stroker, you are changing the VE of the engine and I would be leery of assuming that the factory ECU fuel and timing maps are still safe.

Its how we've always done it with no ill effects. All he has to do is let Vishnu know the injector size and the fact it has a stroker before they complete the flash.

The fueling will be a bit on the rich side, the timing will be low, and the boost will be very low. But he'll be safe to drive it up to AMS in Chicago.

I answered this question several posts ago. I guess no one read what I wrote.

Hehe, that's what I get for trying to speed-read.

Anyways, I clarified my statement a couple of posts ago. My experiences with the XEDEflash on a built 2.0 liter have been mixed. I ultimately had to go with a full custom reflash of my ECU and I can't imagine that a 2.3 would be any easier. Then again, it could be just my car.

So with just the addition of a Stroker AMS 2.3, and injectors, leaving my mods the SAME outside of those 2, my gains will be in the TQ department, and NOT the HP department correct? Any input would be appreciated. In order to get the car home, I should take my ECU up to AMS for them to flash it to driveability correct?
