  1. Bumping this topic... I'm surprised no one else has interest in this. OEM systems I have worked with do this, and it makes sense. At low throttle openings, a change of throttle angle is a better trigger for transient fueling than map for engines that have low / noisy idle vacuum. However, at steady throttle angles, on a turbo engine, as the boost builds, there can be a need for additional fueling, otherwise you get a lean spike. I've noticed this when tuning steady state and then doing transient sweeps, if you tune to the sweep, you get a inverse V in your fuel map. Certainly this is not
  2. I've noticed on some of the cars that I've tuned with G4's that it would be good to have both accel fueling strategies available at the same time. Primarily I use tps based accel fueling, but on some turbo engines, you can get a bit of leaness when the turbo spools, and tuning with map based accel fueling alone is not much of an option on engines with decent sized cams.
  3. Adam, I am familiar with those three widebands you mentioned however I believe the price point is either too high or the quality is questionable. my thought is that if they could offer a CAN wideband including the sensor with a street price around 250 dollars that utilized the lsu 4.9 sensor, or for about 350 dollars that would support / utilize the NTK sensor (4 or 6 milliamp)they would have a real winner. Besides eliminating the voltage offset, Link offering their own CAN wide band would allow them to implement warm up strategies that would protect the sensor and reduce sensor failures, in
  4. I know that link recommends the Innovate wideband, however I've had very poor success with these in the past. I would like to see a reasonably priced Link wide band with CAN communication, and support for at least the LSU 4.9, even better to support the L2H2 (NTK # LZA-09-E1) and/or production NTK sensor (NTK # Â LZA-08-H6). Any plans along these lines ?
  5. I was wondering if anyone knows where I can buy, or could give a specification, for the wire type that is used in the flying lead harnesses. I'm in the US, TXL and GXL wire is common here, as is mil spec, but the stuff that's used in these Link harnesses appears to be PVC, and looks similar to the wire that is used on a lot of Japanese vehicles.
