I had the great day at JP's(Unique Autosports) Monday, Ben fixed my engine probs straight up, he diagnosed it perfectly and had it fixed in no time:thumbsup:thanks Ben. So my Zed was fit for the Dyno to finally test out this PDA I have with the ecuXtend programme on it. The manufacturer claim 10% power increase(minimum), I was sceptical but wanted to see. We left the car just as she is every day, 11-12 psi boost. And was I happy with the result!! The red line is without the PDA tune, 190kw, and the blue line, with the puuurrrfect A/F and the extra 18kw is after Ben tuned my stock Nissan ECU using my PDA with ecuXtend software. 18 sweet kilowatts :zlove: I thought I was at my limit power wise with stock internals, stock turbos(auto)and stock side mount IC's. AND its not lost when I turn the car off, its there till I choose to change it.......not about to in a hurry tho damn she feels good! So whens that night at the drags Oni ????
Well done Caz.. that's one mighty fine looking graph you got there. That's quite handy Caroline, 18kw extra. Go the silver Zed :thumbsup: :thumbsup:
Personal Digital Assistant, see pic, its a small portable touchscreen pocket PC. It runs Windows 2003. Im no photographer as you can see, but this is my PDA. The controller(on the left) is now mounted in my pillar pod.
You are able to adjust the ignition and injector timing independently (and load them to macro)to achieve the best performance possible for your particular engine and mods, safely. All our engines are at different stages of ware,different oils/fluids, different spark ect and this allows you to customise your Nissan ECU to your own engine. I think by 'global changes across RPM' you are saying that this system doesnt allow you to tune only a particular rev range, like you can with aftermarket management, and you are correct ,it doesnt. It isnt aftermarket management, doesnt carry the purchase, install or tuning costs of aftermarket management either. I couldn't have been happier with that dyno result tune wise, perfect steady 12 A/F..good power curve.
so do you run engine at certain rpm on a brake dyno, the tweak timing and fuel, then change rpm and tweak again, noting results and then burn to custom chip? if you just change global timing/fuel values, sure you might make better peak, but rest of curve will suffer (which doesn't seem to be the case from the dyno graph). eitherway, looks like a sweet setup. what is that next to the pda, is that some sort of wideband af gauge?
Ben at Unique Autosports set it on their Dyno, I'm not familiar with the term 'brake Dyno' sorry.(except when it relates to Wizard:LOL The map is not tuned in bits, so is not an expensive thing to get done and you're right about the graph! cant see any point in that curve that could be improved on. Could that be Bens experience with tuning Zeds maybe? The adjustments/tune are saved in the PDA in one of 3 macro's ,no burning chips or pulling your ecu out. The PDA connects to my consult port and has a digital dash mode that shows me which macro I have currently selected and its settings as well as speed,engine temp, RPM, air flow, inj cycle, timing and 02's. Also has engine monitoring screen, active tests, fault code retrieval and clear, datalogging and graphing, 0-100km speed trial,a shift light with with a 12v switched output to bring in an accessory like a IC spray,elect fan at that rpm. The control unit is gauge size and contains the charge unit for the PDA and shows me power on, ECU read and receive and a very bright blue shift light. With the shift light function the top half of the PDA goes a bright luminous green/yellow too. And its still just my PDA that has all the stuff you normally have in a PDA.I just think its clever:thumbsup:
