A few tough ECUTEK questions....
I guess this is directed to Shiv because he's the only one offering them at this time.
I'm leaning very heavily towards getting a ECUTEK reflash in a month or two. I have a VF29, and will be getting fuel mods. I have a catless up and downpipe, with an exhaust cutout installed before the stock third cat. So at the track I take the cover off and have a 4 foot long open exhaust after the turbo. How will the ECUTEK's boost control deal with this? Do I need to mess around with restricors in the lines to control boost? Not a big deal I have a needle valve already installed to prevent boost spiking with the stock boost control. What does the ECU rely on to determine timing? There is no post turbo IAT sensor, so how does it determine the quality of the intake charge, if it is hot or cold? MAP/MAF/RPM/cc's + the ideal gas law? I have read here that with the stock ecu there is no active control of timing after 6200 RPM's and that it is basicly set from feedback from the knock sensor...is this true? I felt this in my car when I installed the large turbo - very agressive timing up top at about 12 psi - for a little while. Does this continue to be true with the ECUTEK, or is the active timing range extended? Can the rev limit be raised slightly, say to 7400 or 7500 RPM? What about high octane or race fuel? Not leaded fuel, but a few gallons of 100 oct at the track, or 94 oct plus Toulene on the street. Will the ECU respond with strong timing or to a change in AF ratio from the fuel? Shiv seems to be the only one offering this right now. Will you be travelling to the east coast at all for dyno tunes? I live close to Adreniline Motorsports (which has a Dyno Dynamics) in Worcester, MA. I belive Vishnu has offered unichips through them in the past. I'm sure there would be enough interest for many people in the area to get custom tunes over a few days. Thanks, Kevin

Bill at www.I-SpeedUSA.com (aka skywalker),
Just curious to know whether you guys are currently using an ECUTEK reflasher and have the benefit of access to their guides, training materials, etc. If not, what is the basis of your assertions in the post above? |

Yep I-speed is using the ECUTEK reflasher. I was just looking at the book last weekend.
