AMZ1- Is it worth the new flash?

[Flatliner]

Well there was a thread started on Modular Fords about this... and many have put up their dyno sheets... some interesting facts being brought up.

1) A/F across the board Richer
2) Looks like Ford richens up the A/F at 6k...
3) At 6k... power seems to die off
4) Some reports of loss of power on same dyno machines about 30hp.

I think some of these have to do with why my car feels the way it does along with the belt slip.

I also have the flash, and have been noticing a power drop right at (maybe even a little before) 6k. I thought I was hitting the rev limiter at first. I am also starting to wonder if I am still having a problem with my FRP sensor.

I hope that whatever ford did, can be fixed with a new tune....

 

[Flatliner]

Carl, these can be adjusted with a new tune such as Predator, SCT, chip, etc. It is just disappointing that they did that.... at least it explains the SS race, I really was shocked and expected to pull on him but didn't

Why do you think you are still having issues with sensor? Did your check engine light come back on?

 

[Wiked03]

The light hasn't come back on. But the car seems to be falling on its face right at or before 6000 rpms, which is what it did on the dyno the day the sensor blew. When I got the senosr fixed I also got the flash, so now I am thinking it may be the flash and not the sensor. I don't normally ride it out that far anyways, but I didn't think it should do that until I hit the limiter, which I thought was around 6500.

So I don't know.

 

[Flatliner]

It's not the sensor, it's definitely the flash... check out the dyno sheets on the thread, they are all doing the same thing. Time for the predator/ SCT... that will cure it. Of course you could ask them to reflash what you had... think they would?

 

[Wiked03]

Dunno if they would, but I don't think I want the old program back anyway. At least this one doesn't stall constantly.

 

[Wiked03]

So what do I do for MSC? Just shift before 6k, or should I try and get tuned before then?

Is that the flash for the stall fix?

 

[SVTspeed]

Some of the drop offs at the top end are a few "over temp" variables thar Ford has. They should be very apparent when the car is pretty warm. The latest preadator would not adjust 100% for that, depending on who does a custom file and what templates they have it would have the fix. Not sure about the SCT. I don't think there are templates out for the stall fix calibration, I'll check to see how that is doing.

 

[Wharf Rat]

So if you are planning on getting a pulley and custom tune in the near future you would be better off to NOT get the stall fix from Ford first? Can a custom tune fix the stall then? I got it bad h:

 

[SVTspeed]

Would not matter. The chips temporarily replace all 4 banks meaning the stall fix flash would not even be run by the computer, it'd go off the chip. And the chip does not have the stall fix.

 

[SVTspeed]

The stall fix template is still in the works. Sounds like it will be a few days. If anyone has the problem that I have previously tuned they can bring their chip in so I can read it and transfer it to the new template.
