Mine does the exact same thing, drives me nuts... Would love to have a solution to this, my past turbo diesels had a nice linear acceleration and my Eco is completely schizophrenic unless I am deep into the throttle. It does it a bit stock and bad with the 87 and 91 Perf/Tow tune...

tuned tiny turbos and boost controller response (n75 valves on the vw). my vw with its k03 and downpipes would want to go go go go depending on throttle input and do what you describe. Would be even worse if you used a manual boost controller. Especially once i switched to corn and started to run crazy timing advance. It got so bad that it would respond like a light switch. Seemingly full throttle or no throttle lol. On the vw the stupid tuners sometimes would also edit the pedal response map meaning less pedal gives you more throttle, its a false sense of increase power.

Requested load is the name of the map. Another piece of awesomeness brought to you by DBW vehicles.

Have you had any tsb's done? I had this same feeling stock until they did tsb 13-3-3 which included a new ecu flash. And im assuming you have 5 star as well

Is your timing dipping as low as mine under load? -15??

How do you check for grey codes?

I use the android torque app on my phone

XFJunkie

I will let you know, my TS SCT and tunes from eric@ID arrive tomorrow

I need some guidance on android torque app, i also hear it will read strategy, rather go ahead and get that over to eric to have the tunes mailed back.

Let us know how that tune goes, I am always in the market for a tune if one blows the doors off the current "main-stream" like Livernois, 5 star, MPT and now Unleashed.

Brett, if/when it comes back, then give mike at 5 star a call and mention the "how the computer pulls from the timing tables" thing along with the sproadic spark and he should hopefully know what you are talking about and should be able to modify the tune to pull data correctly to smooth out the spark advance from the huge swings.

I don't think I can clear mine, they say "n" drive cycles. Fill me in on your process to clear them ,lol.

JUST FYI, my table at idle are always advanced like +16 to probably +27 (this is on the 93per tune). That's why I am saying that regapping your plugs might now mean that you could take extra timing that wasn't available before...

I just check for dtcs on the torque app and then clear dtcs. Run the dtc again and no grey codes.
I'm so cunfused about the timing lol. I gapped the plugs while the truck was stock the loaded the tune.
Anywho I reset the ecu and did a kam reset last night. Right now it's running fine.
I sent mike some emails but got short answers. Not like "ok lets see what's going on here".
I'm going be upset if it starts acting up while pulling a boat saturday
Oh and I'm hovering around 10d timing at idle with 87 perftow
