I talked to a Dobeck rep today & we discussed numerous things & like most of the places I called their product can do everything I need it to do. Between that & all the good threads & comments on here about Dobeck, one would think I’d be sold. However, there is just one thing that bothers me about the gen 4 unit, it only has one sensor. The rep says they usually put it on the front pipe. I should have asked why, but I ran out of time. If you have a unit that does all that it says it does & the system comes with a gauge to adjust & prove that it’s doing something, why not refine it & get data from the rear cylinder pipe as well? The rear runs hotter than the front anyways, I know mine does. I also heard & read that a proper mapping is the mapping of both cylinders independently and you go from there, so why not get sensor data from each pipe? I guess I’m getting hung up on that article about POD units sensors having too wide of a band and not segmenting the RPM ranges into small enough portions to satisfy the engine’s fuel & air requirements. I believe you posted that article Glider. I know I’m not pushing a big 103 or 110 motor, but it still concerns me. The price is defiantly better & the no dyno time is appealing, but that’s why I was asking Nitroracer his thoughts on the auto tuners. As it stands, I have a tech that can extract the settings from the PC III & down load it into a PC V and depending on how it runs I may not need any dyno time. Course that all looks & sounds good on paper. My thoughts are, if I do need to get dynode, then I’d get the auto tuner to assist & adjust after the dyno. Am I think off base here, am I over thinking this whole thing?
