Stock timing for GSR with SMC @ 8 psi
For a B18 C1 with JRSC @ 8psi can I just use bigger injectors and SMC or do I have to change timing like Jackson says 10 BTDC?
BTW, the B18 C4 has a knock sensor, dunno if the B18C1 do
Thanks for all advice.

Re: Stock timing for GSR with SMC @ 8 psi (Aerodeck)
Hi,
Thanks for all advice. Did not know that only US newbies get help here.
or does it have any other reason? Sorry for my poor English, anyway it may be better than your German.
And on German boards everybody from other countries receive immediate help.
Better say at least an answer.
So it looks like Honda Tech is a "read-only" forum for me. Thanks again.

Relax, man...the German way --> 
Anyway, the SMC will do nothing to your ignition timing. If you are not running any sort of boost dependent ignition device (like an MSD BTM, JR BTC, or J&S Ultra Safeguard), you will still need to retard your base ignition timing. 8 deg BTDC for 92 octane, 10 deg BTDC for 93 octane.
A lot of JRSC cars don't require much ignition retard under boost from 5500+ (VTEC). However, from 2500 to 5000, most Hondas/Acuras seem to be very sensitive to detonation.

Re: Stock timing for GSR with SMC @ 8 psi (Sonny)
Thanks Sonny,
I already thought to have broken some of the unsaid board rules and therefore nobody replies
Anyway thanks for the first advice. Please let me add another question.
Here in Germany I drive 99 octane so which would the retard then be?
Also, without one of the named devices I think I cannot retard timing just in lower than 5500 rpm's.
Then, I actually wanted to get the complete JR upgrade kit but I heard that the BTC is crap (I also do not need the complete kit, for 8psi just SMC and 440's, maybe spark plugs) and the Safeguard Ultra is too expensive.
Unfortunately I do not know any other option. Do you have an advice?

What does that mean?
It only modifies MAP voltage which will not affect your ignition timing.With 99 octane, I doubt you will have to run much retard (if any). Does your engine have higher compression than the USDM engine?
I would start out at 12 BTDC and keep advancing until you hear pinging. You will most likely hear it around 4500 if your ignition timing is too far advanced.

Re: Stock timing for GSR with SMC @ 8 psi (HellSing)
The compression is 10.5:1.
The thing with the MAP voltage is certainly part of your common knowledge but here in Germany NOBODY does have any experiences apart from the tuning companies.
They do not "share" their knowledge without emptying your pockets
Cant I just use the SMC and a fuel air gauge to ensure that I do not run neither to rich nor to lean?
According to my "amateur" knowledge I thought that pinging/detonation happens only if my engine runs too lean. So if I provide a good a/f ratio there shouldnt be any probs, or yes? This is the point I dont understand. If the afc hack always provides the mixture I need why should the engine ping?
Thanks for helping an overseas amateur.
