I'm looking to find tunes for my 99' zx2 auto. Who has tunes for the car?
All I have done to it is a 180* T-Stat, nothing else. I am looking to get the transmission to shift a little firmer and the cooling fan to start 15* sooner. I would like a 89 or 93 octane tune if possible. What gains will be had by the SCT? Who sells tunes for this car if I have a blank SCT tuner?
The car runs fantastic and has 202K miles..I have been meticulous about the service on this car.
Forgive me, I am new here.
Thanks,
Dusty

Theres not too many SCT guys on here. You might want to give SCT a call and see if they can set some up for you for what you want. They are pretty easy people to work with all you would have to do is tell them what your pcm code is.

You need to find an SCT dealer that does custom tunes. I know that there are a couple of guys on teamZX2 that do SCT tunes but expect to pay $50-$75 for one. Most of them will tell you to throw the automatic trans out and swap in a 5 speed.

Remove the front half of the center console and read the sticker on your ECU.

It will be a 4 digit/letter code for example mine is DTD2. If i had a zx2 i would make a tune for you.

If you don't mind spending a few hundred, the best tune you can get is from a dyno shop. Any dyno operator that is experienced at tuning EEC 5 Mustangs can get your Escort a worthwhile improvement in both power and efficiency.

what year is your 3rd gen and what flash device do you have? 5spd or automatic?

I have 2002 SE automatic. Tunes were done with a SCT X3 at Vang's Dyno Performance, in Tulsa. My older daughter is driving the car at college now, but she has to give it back when she graduates. I have three tunes in the X3, mostly changes in timing from stock, but some AFR tweaking too. Some of the guys will remember me; I haven't been on much the last two years, since the car has been 100 miles away with my daughter. The performance mods began when when the #4 (what else) intake valve seat dropped, trashing the head and all four pistons. So I had another head cleaned up and had proper seats installed, Three-angle cuts on the seats and valves. I then gasket-matched and ported everything from the throttlebody to the headers. I had the head bench-flowed three times during my porting and it now flows some 12% better at stock lift, 15% better at .450 lift. I have the Escort-Focus 1C1C18R camshaft. Custom bent 2-1/4" exhaust with a Dynaflow metal matrix catalytic converter (mounted under the car, since it has a header now) and a Delta 40 muffler. Before I had any dyno tuning done with the setup, it dropped the 0-60 time from 11 something down to the mid 8's and 1/4 mile from 18's well into the 16's according to a Dashhawk. Programming the tranny to shift at 6250 and fixing the god-aweful slow shifts, tuning in much more aggressive WOT ignition curves, and trimming the AFR down around 13:1 at WOT has yielded an increase power at the wheels of about 30%. But peak numbers don't tell the whole power story. The increase in area-under-the curve is tremendous. With the 91 octane tune, the Dash Hawk is telling telling me 0-60 in the mid sevens and 1/4 mile in the mid fifteens on a 78 degree F day. And that is about all we are going to get from a completely street-driven-friendly N/A 3rd Gen SPI sedan without doing a weight reduction. A 50 shot of NO2 will put it into the 14's. Anyway, a dyno tune on even a completely stock SPI or ZX2 will yield a very pleasing increase in performance, because the tuner can read the engine operating parameters in real-time and adjust the timing and fuel curves on the spot.

My question was actually to depatt since he wanted a tune :p sounds like you have a decent list of mods though. You would be much happier having done those mods with a 5spd though rather than the auto.

The 5-speed swap is going to happen eventually. I ran out time before the kid headed off to college. My goal is to eventually get it autocross and SCCA Improved Touring B Class ready. Most of the head work, and certainly the non-stock cam are not technically allowed in Improved Touring, but practically nobody knows enough about the SPI engine to make a teardown challenge. And, in the U.S. anyway, nobody wants admit they got beaten by what appears to just an Escort sedan with with a header, an intake, and a really good tune. Racing an underdog has its advantages:)

My car is a 98 automatic...As of right now I don't have a flash device, but I plan on picking one up soon when the rest of my tax money comes in. I've already looked into getting the 5speed and know I'm gonna do that down the road. I just want the tune to see if the car would run better with what's all done to it in the mean time. Just taking my time with everything..Might just take it to a dyno shop if that ends up being cheaper..

@F-16 Wrench..You have a crazy number of mods, that's a long list for n/a and it's auto..But my car runs strong with all that I've done to it. I just haven't had the ecu flashed and I'm wondering if it would be even better with it flashed. I'm just trying to take my time with everything and to have a solid tuned car.

Computer tuning on a dyno (if done by a dyno tuner truly knows his tuning theory) will gain you some level of overall power and efficiency. I would do it, if you have the money. The trick is to find a shop that really knows how to extract max power at WOT without crossing the grenaded-engine threshold. Most OEM tunings leave a massive safety margin in the interest of warranty and a customer base that cannot be counted on to maintain the vehicle in perfect condition. A stock vehicle has to last a reasonable amount miles even with the worst mis-treatment/lack of maintenence. If I had to take a WAG at it, I would estimate a bone-stock SPI can gain 5 Wheel-HP and 10 to 12 Wheel-torque from a really sharp dyno man. You won't get that much using some else's pre-written tune. And, a good dyno guy write several tune levels and load them on to your flash tuner.

Yeah I might just go with the dyno for now ..but I know I wana get deep into tuning, modding, and learning everything so I can to be hands on with it..so I'll pick up a flash device later on down the road when I'm deep into all that I eventually want to do with the car..
