Jellybean Posted February 12, 2015 Author Share Posted February 12, 2015 Sorry to keep asking , maybe I missed the answer Do you still have to adjust the vernier pulleys on the dyno after your work with the degree wheel and dial guage ? or the cams are setup manually or mechanically now ; you just adjust the timing electronically ? Can you adjust the timing on the dyno with a standard ECU? Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted February 12, 2015 Share Posted February 12, 2015 You don't have to anywhere near a dyno if you don't want to, provided you are happy with the nature of the power delivery after the cam installation. There are two types of timing, valve timing & ignition timing. With a standard ecu I don't believe that ignition timing is adjustable, save what the ecu itself deems necessary for the engine to run properly. You can adjust the valve timing via the vernier pulleys to alter the power & torque curves, within reason. Quote Link to comment Share on other sites More sharing options...

Can you adjust the timing on the dyno with a standard ECU? You need a reference, then if you wish to play you know where the start position is. If you *do* wish to play you need to know how far either side of the reference it's safe to go to avoid valve to piston, or valve to valve clash. This is something much more easily ascertained on an engine stand with soft valve springs and easy access to the engine and the timing wheel.

Jellybean Posted February 24, 2015 Author Share Posted February 24, 2015 I am do a little bit of night time reading A.Graham Bell Four Stroke Performance Tuning Very interesting so far and oil temps/oil coolers / Race Thermostats for the Rad So , he said to for running in The Cam bearing journals are taped and the cam is plunged into a high temperature bath of Phosphate acid to which etched open the pores of the cam so that it may retain oil more effectively , this is the lubriting part of the process Please dont tell me I need to do this I need to re-read the chapter again but I can comprehend what he says , but I think you really need somebody with experience to setup the dialler and degree wheel ; its one of those things , sounds straight forward in practice but its experience that executes it correctly Alot of measurements in here about tappet velocities and Measuring cam Characteristics/Accuracy , plus using cam timing sprockets versus Vernier pulleys to time the Cams, valve fouling, calculating camshaft Timing Diagrams , calculating vale spring pressures I think I will need to re-read the chapter a few times Quote Link to comment Share on other sites More sharing options...
jumpbike Posted February 27, 2015 Share Posted February 27, 2015 is there not another concern amongst all this that fitting 264's with the standard ecu is going to cause it to idle badly and the fuel mixtures to be lean, plus the whole stock timing map will be out in relation to where the peak torque etc. now is in the power band Quote Link to comment Share on other sites More sharing options...
Jellybean Posted February 27, 2015 Author Share Posted February 27, 2015 Memebers are running them on Stock ECU's idling like OEM ,they are not getting the max potential out of them but they are working fine Tomei also said I can use a stock ECU, I have a Sard Analyse rom in mine ; will throw her on the Dyno after to check everything Quote Link to comment Share on other sites More sharing options...
