SPArKy_Dave 8,829 Posted December 30, 2015 INFO COPIED, PASTED AND LOGGED - FOR ARCHIVAL PURPOSES It is pretty close to stock - just the head shaved and cam ground to 208@50. I'm bypassing the EST computer, and just using the EST pickup and coil drive,- also the EST advance map to start with. Essentially, its like I can run the EST at 30 degrees base timing without it pinging on either gas or 95 petrol, and I figure for that to happen something can't be really right. I've just been checking the cam timing, and its looking ok, but the theory I'm working on now is that there's too much lifter pre-load. There's nearly 2 turns after the rocker contacts the pushrod. Not sure if it's actually causing a problem though, because it's still giving 175psi compression, so presumably the valves are closing off. Anyhow, about to put some shims on the pedistals to see what that does. Share this post Link to post Share on other sites
SPArKy_Dave 8,829 Posted December 30, 2015 INFO COPIED, PASTED AND LOGGED - FOR ARCHIVAL PURPOSES whats your total timing? Share this post Link to post Share on other sites
SPArKy_Dave 8,829 Posted December 30, 2015 INFO COPIED, PASTED AND LOGGED - FOR ARCHIVAL PURPOSES Stock EST total advance is 36deg I think. My 60thou off c2 combo runs stock 86 ulp est and doesnt ping either cam is 214@050".I may look for a 200xflow est ecu also apparently these ramp up quicker.

Mr Polson 10,214 Posted December 30, 2015 I gather from past threads that the 3.3 (and maybe manual) versions have less RPM advance. I know your only archiving this, but don't think 3.3 ever had EST? Correct me if I'm wrong but the 3.3L was deleted when the XF II came out in 86, which was when EST was added? Share this post Link to post Share on other sites
slydog 7,873 Posted December 30, 2015 Corrected...3.3 was used in XF. 3.3 EST timing comp was the one to have over the rest as it had a better curve. 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites

CHESTNUTXE 7,260 Posted August 24, 2017 Hey dave im thinking of buying this 1992 xf ute which is auto,i want to fit my manual conversion to it,do i need a manual computer to make it run with all the factory est gear hooked up or will it still go with the auto computer ? also is there a later model ecu like a xr6 eb or ed that will plug straight in for better performance ?

deankxf 20,231 Posted November 30, 2017 why cant you get a sender with a different range, so say if the engine does get HOT it will pull timing out.. would have a range rating on it in a book somewhere i'd think Share this post Link to post Share on other sites

I've done research and many vehicles are fitted with similar map sensors with identical plugs. Sent from my SM-G930F using Tapatalk Share this post Link to post Share on other sites
