Here's a tweak that'll cost you nowt:

I wouldn't go playing with the timing on its own unless you know what you are doing, and have money for repairs ;)

"Hello Shell, I'd like a tank full of your finest 7 day old petrol please...."

 

Be very very carefull playing with the timing - one bad batch of fuel and it could be bye bye engine. The standard timing is set so there is some margin for poor fuel - take it to the edge, get a bad batch, and listen for the detonation.

Of course, if you run your car on race fuel every day, this shouldn't be a problem :)

When you say bad batch, do you mean lack of octane or "flat fuel" or are we just refering to anything other than Mr. shells finest ?

Just thinking that if it's low octane, then maybe we could take out socket set and a few bottle of octane boost to santa pod and do a couple of runs to see what the difference is.

 

1) First run normal 15 degrees (i.e. stock)

2) Plug the Conzult in and adjust to 17 degrees and add some octane booster octanne booster.

:D

 

Can you alter the timing using Conzult? How does that work then?

 

What about an "Octane Rating Detector" © P.Shrimp 2003 installed in your fuel tank which then advances or retards the timing depending on it? :D:D

Nope you can't alter it via a conZult but you can monitor it via a conZult, and adjust it by loosening the bolts and rotating it.

Erm, nope ;) The timing you see on the conZult is based on the ECU thinking that the CAS is set to 15deg. If you change the CAS, the ECU will not know about it, so neither will the conZult. Unless I'm completely missing something here....

Some years ago a guy who works for Omex designed a gadget for the S12 ( for SE Nissan) that allowed you to advance the timing quite abit for quicker acceleration, then retard it back at set points at higher boost and revs to avoid detonation, worked really well.

Always wondered if it would or could be made for the Zed.

Wouldn't reccomend anyone advancing the timing unless you got soemthing that can alter it automatically further on the rev band,

Not good

:(

Thats a damn good idea and yes, I'm sure it would be possible on the zed - the CAS (which is all the ecu uses for the timing) simply outputs signals at 120deg and 360deg to the ecu - as long as you change them both I don't see a problem. Now just need an electronics wizz - OR get an apexi ITC lol

A'pexi ITC

 

Interesting :D...

I think the guy who designed it still works for Omex, Richard Ragg i think, he knows his Nissans cos he drives one :D

SE would never say he supplied them the units :rolleyes:

When i ran my Silvia with it in, **** was it quick, big difference in power, it also doubled up as thief deterrent, cos once unplugged from it's loom (inside the glove box) car wouldn't start, handy :D

smithy

:cool:

Apexi don't do the ITC anymore from what I can see. I'm sure you could pick one up on ebay though. Another option in a similar price range is the greddy emanage but now its getting complicated. Of course, a custom mapped chip achieves exactly the same results too - or should do ;)

I've heard the TDC sensors are very sensitive - so don't go playing roughly with them !

Yeah gotta agree there - I shouted at mine once and it didn't talk to me for weeks.
