Is there anyone who had done a dyno run, after they installed the MTH ECU flash?

If so, is it a smooth map? Are there any flat spots? Any dips?

Better yet, could you post the map?

 

I am going to have my 2005 MCS dynoed tomorrow. It is stock except for the MTH software that was installed 3 weeks ago. Assuming the dyno gets done I'll be happy to post the results.

I will say that subjectively the car's power band feels smoother and stronger than the original map.

Will you be also running it without the MTH?

 

Depends on whether or not the club member with the laptop and cable shows up and whether additional runs are available! It's a MetroPlex Mini (www.metroplexmini.org) "Dyno Day" event. I've bought three runs already and will buy three more if they're available and the car can be reprogrammed. Matter of timing and availability.

So what are you doing it for? Setting a baseline for future mods?

 

Grins, comaraderie, observe other folks mods, deplete the world supply of oil for no productive reason, that sort of thing. Plus, we're all meeting for "breakfast tacos" and it's terribly important to me that I get my share of those.

 

That's unfortunate...not for the fun part, but because one run won't produce any actual data :( I'd like to see exactly what MTH is pulling.

 

I don't see what you're getting at. Three runs will produce plenty of data for one configuration. And if I get the other three runs in without the MTH map then I'll also have a baseline. It's just a matter of how many runs are available - I didn't want to be a pig by prepurchasing six runs because that could well keep someone else from getting their car dyno'd during the event.

 

Here is my Dyno runs...


they were done on the same day.. the orginal map was loaded and the car reset as a baseline.

the MTH was then uploaded and the car run for only a couple of miles..

you can make your own observations....

 

Whoa!! Why so rich? Even with a computer reprogram and you are seeing 10:1 at 5500 rpm? Seems strange to me

 

I think MTH improves the car, but I don't have data like that. I also think that with good data logging, the maps could be improved even more! One time I asked Franz if he could reprogram the ECU to use the output of a wide band, and he said yes, but I haven't done anything about it....

Most of the dyno's I have seen are similar..

this is why apexi is a good thing..


I am not a mechanic.. and I dont' play one on tv..

 

I'm simply saying - if you don't make runs with different equipment, it's meaningless. So if you can't flash to stock from MTH, you're just doing it for fun, you won't know how much the MTH adds - that's all.

 

Exellent post with the chart! This is the kind of data we wanted!


Now the question is - how do we get Franz to improve the mixture?

 

Compare that crap to a unichip and youll see why its worth the money. MTH sucks, GIAC sucks... Ive never seen them break a 5hp gain. the apexi is good for the money, but the unichip is able to tune 2x as many paramters. This allows you to not only make more power, but also improve drivability. Compare before tuned (the map that came on the unichip) to after tuned.... keep in mind that the car pulled timing on what SHOULD have been my best run (knock sensor).

Even with the motor dropping 10hp after the knock sensor kicked in, I still made 6hp and 12ft/lbs of torque more than the program that comes on the unichip. Should have been more like 12/12, but Ill have to do another dyno pull with better gas to prove that. Oh, and just look at how much the air fuel ratios improved

Bottom line, **** flashes.

 

If you look at HP per $, the MTH is a good value. No one is gonna argue that custom tuning your car is better than a "canned" tune. Tolerance stacking and regional gas variations guarantee that.

Same thing with my mustang. But that was at the point a factory tune wouldn't run worth crap. Had to get a chip. Car ran good, and power was decent, but a dyno tune found another 12 HP. Does that mean the chip sucked and I should F it? Nope.

Also, MTH has tuned the Cosworth maps for M7. It would be interesting to see that A/F data. The control maps are all changable (if you can get into the code....), so you just need enough data logging to really dial it in. If the OBX ever gets back in stock, or the Pilo Racing Header comes out at a decent price, I plan on doing a wide-band for logging.....

I got very improved driveability, a little bump in HP and torque, and most importantly a detuned TCS for under $150 with MTH, plus I can update it with different maps or back to stock at will. I'm sure others make a little more HP, but frankly it's not much and certainly not $500+ worth to me.

 

I got exactly what I wanted with my MTH. Improved throttle response, the elimination of a high RPM flat spot, and all around better driveability. Money well spent in MY opinion.

Dr., I've got the DPR racing version head and while its quite pricey it rocks . Have you seen the chrracingproducts headwork. Good price for the flow numbers.

 

Come on J, for the money the MTH does a damn good job. Like the Doctor said, you can't beat the dollar per HP numbers that the MTH provides. Yes, you can get the Unichip installed and custom tuned for 7 bills, but you've dropped 5 of those bills for double the HP? Does not seem like a great return for the money. But that is just my opinion. I would rather drop the extra 5 on other goodies that don't cut into the wiring harness and add extra points of failure.

 

Don't want to be picky, but the Unichip is plug n play. No cutting of the original harness is necessary. You simply plug the original harness into one that lies between the Siemens and the Unichip. 10 minutes to put in and less to take out.

I'm just glad there are different options for folks to choose from. Some folks place a higher priority on value, whereas others on getting the more costly ponies out and cost is less of an issue. To each his/her own .

 

The apexi requires the harness to be cut into.

 

I don't think JCampos got his gains until the unit was tuned for his car. Proving once again that no matter how good a solution, the canned ones aren't perfect... Custom tune is the way to go if you want the best bang for the buck. But until you get a way to log, remap, and reprogram at $0 a turn, custom tuning is pretty expensive if your mods aren't done..... Even at $100 a turn, if you could find that, I'd be into $400-$500 for tuning alone, and I've just really started the power quest (more to come....) I think with an Apexi or some other home tuned device, a good GTECH dyno (or one of the other intertial ones), a wideband and some data logging, you could actually tune your motor pretty good for pretty cheap.

Looks like this sort of evolved into another MTH - UNIChip comparo...

Threre are several threads on this apples to oranges subject, and I think this is one of the more recent ones (starting at post #44):

For those who see themselves mod'ing from the intake to exhaust, and everything in between, the few extra bills will most likely be seen as worth it to those folks...

 

I recently had a similar dyno run with my slightly modified 2005 MCS (15% pulley, 62 mm TB, Alta CAI and one-ball exhaust) with MTH. I then sent the dyno results to Franz and he was able to change the A/F ratios. The A/F ratio no longer falls into the 10s at high rpm but still runs rich enough for safety. My last dyno run with 95 octane gas was 194 WHP and 176 ft-lb torque. If you send me a PM I will send you the before and after dyno chart.
