There is debug mode for custom maps. It defaults as debug mode unless you deactivate it. So if he was doing something custom its possible. There are still corners of the ECU I as well as likely the majority of tuners out there haven't tested every scenario with. I need me a damn car so I can test 10-20 flashes a day on my commute to and from the office. lol Ive managed a good 400-500 flashes in the six weeks or so without a car... I wonder what I would have if I had a car in my driveway right now.

After a few quick flashes just smoothing the fueling out the power was nearly the same, so if regression from a few pulls is what someone is talking about I don't know what they are talking about since I would have seen a power "gain" from flashing the rom with almost no changes. There are a lot of tables in this ecu so it is possible something was forgotten if they were getting regression.

I was not a few pulls, It was repeatable from what i recall. First pull would give X every pull after that, be it 1 minute or 1 week in between the results would be X-n at one specific point at the begining of the dip area.

I think JB just needed a bit more time with the car and software. I offered to take a look at the logs at the time but never saw any. I'm sure it's a simple issue. Probably related to the oil / coolant temperature or amount of time after flashing before running the car.

Holy Jesus, is that all on the same car (the flashes). Are you concerned with the ECU going bad?

No other changes other than a second pull. The first pull (blue) is immediately following a flash, the red following that. The advance mulitplier was lower on the blue which explains most of it, but additive timing kept the over all timing within a degree. If the dip was limited to that amount every pull then you would never know what was going on unless you were being picky.

Here is the specific post everyone is referring too as the "regression" issue.

One specific car that i use for general testing I have flashed ~225-250 times. I have spent a long ass time staring at that tach watching it flash. lol

To quote my self from the ft86speedfactory header thread:

Respecfully at:
RPM ENGINE LOAD
800 0.880
1000 0.900
1200 0.890
2000 0.919
2200 0.919
2400 1.070
2500 1.109
3000 1.099
3200 1.299

If your vehicle pushes over these load limits it will us methods to limit timing, and iirc fueling. However the torque dip starts right after this point. A large difference in the torque dip is made by tuning the cams in the car. Most headers let you tune the cams further and gain some additional power in that region.

So that somewhat lines up with the RPM range of the OEM load limiters for low RPM.

Nameless must be making some serious cash right now

@jamesm @mad_sb. I'm not trying to drag you in to anything, but have either of you had issues with runes "regressing" back to stock after only a few dyno pulls? I know the other guys can't post here due to their vendor status and the whole "stay out of other vendors threads.

There was something about some stock ECUs messing with IAM, and some don't. Probably the issue.

The MoTeC will not be the problem.

i've extensively logged thousands of miles of driving with every tune revision i've made (200+). i've never seen anything that would in any way indicate the actual parameters of the ecu (fuel target, timing, cam angle targets, etc) changing at all. if you're seeing a change in performance from pull to pull, it is very likely due to fine (or coarse) knock correction being applied. that will cause you to lose some power real quick, and sometimes won't show up until you've done a couple more pulls or have been out driving for a while.

there's no logic by which i could deduce that the ecu would change in any way over time with an ecutek tune or other reflash. with a piggyback, sure. flkc or an iam drop will, however, show up over time and reduce performance (often dramatically).

Exactly, looking back over some of my older posts, it seems JB did not have the IAM set to 1.0 so I'm fairly certain most of what was seen was related to ignition learning and possibly with the low rpm load limits.

I see they dropped the sale.....

Looks like i'll be going elsewhere, 1350 was a stretch, 1500 i can't do.

[Dustin]

^^^^^^^^^^ Which is why I ordered mine before the price went up. $1500 is a bit steep.

That's only if you get it with thermal coating.

You COULD just buy without ($1200) and wrap it.

[StormTrooper]

Yes you could.....

I would have bought it at 1350 but i needed my tax returns. .....so in about 5 days.


Now i might as well wait to see if it really is better.

1150 for 2 other EL headers and 1k for the best uel coated.....

3 questions:

1) Will it fit with the Vortech supercharger?

2) What's the actual tubes diameters?

3) Weight?

@Ryan@Nameless

I dare to re-post my questions with regards to the header design. Since it went into production already I guess at least the later 2 should be easy to answer. Thanks in advance!
