Careless Posted January 24, 2009 Share Posted January 24, 2009 a friend of mine going KA24ET with a big HX35 is going with VIPEC. apparently it's got the berries! the auto-tune feature is intuitive, and from what I hear it uses the same internals as a LinkECU G4. check it!

Xnke Posted March 6, 2009 Share Posted March 6, 2009 Looks like a good solution for the VQ35 guys. VVT and drive by wire built in! Quote Link to comment Share on other sites More sharing options...

Spooler Posted March 25, 2009 Share Posted March 25, 2009 A guy sells these in my area. I am very interested in them and considering it very hard because I am still using the factory ECM with my turbo car. Quote Link to comment Share on other sites More sharing options...

Zardilla Posted May 7, 2009 Share Posted May 7, 2009 I just bought the plugin version for my RB. It should be installed and tuned by end of May. I'll let everyone know how it turns out. Quote Link to comment Share on other sites More sharing options...

Zardilla Posted May 8, 2009 Share Posted May 8, 2009 I paid fairly close to list price, however I did so to get full support from my tuner and the dealer that sold the unit here in the US. That said, if you are going to tune this EMS yourself I would suggest emailing a couple of the dealers down in Aus/NZ as their dollars are currently weaker than USD and the list prices are nearly identical in nominal terms. Of course you wouldn't have access for troubleshooting quite as easily. Good luck. My local tuner (Doug at UP Garage in Tacoma) has installed three of these units (RB25, RB26, and maybe KA) with very good results (smooth power and torque, solid idle and drivability). I'm hoping this is the last EMS I need for my car! Quote Link to comment Share on other sites More sharing options...
fentin_fury Posted May 9, 2009 Share Posted May 9, 2009 After the timing mishap with a certain someone, it kinda makes you wonder whether or not the electronics would do a better job than the humans in this part of town, eh? There are some featues on the Vi-PEC I like - a big one is the closed loop WOT. I also like the multidimension maps - this is useful on an RB with throttle bodies IMHO. Using the TPS as well as the MAP, knock sensor and wideband should prove useful. i still experience some serious flat spot issues just with a MAP - if the system also relied on the TPS this problem could be averted. I figure all said and done with the V88, wideband, ingnition and an external MAP - <$3500. We will see how quickly I can tune it. PS - everyone makes mistakes. Having said that if you promote yourself as the best - you should know some fundamentals. Anyone else here EVER see their boost and timing curves "match" rather than be a "mirror" of each other?

fentin_fury Posted May 10, 2009 Share Posted May 10, 2009 "At any time after tuning is finished the values in the target closed loop table can be changed, and the engine will automatically run the new air fuel ratio" I am not sure if I understand the quick tune. Why not just set your timing, and AFR and run in closed loop mode? Especially because you can do that at WOT. I wonder how quick tune will work on the street - without access to a dyno? q Quote Link to comment Share on other sites More sharing options...
Administrators RTz Posted May 10, 2009 Administrators Share Posted May 10, 2009 (edited) Why not just set your timing, and AFR and run in closed loop mode? Especially because you can do that at WOT. Because a post-calculated AFR is not the same as a pre-calculated AFR. With current technology there is some delay... the distance from the chamber to the O2 sensor, sensor response time, and the ECU's reaction time become a factor with rapid engine acceleration. On a static dyno, salt flat car, stationary engine, etc, closed-loop WOT can work well because the transition rates are either slow or non-existent. A turbo car making a blast through low gears happens too quickly for closed-loop to work properly. I wonder how quick tune will work on the street - without access to a dyno?
