Ok im goin with BC STAGE 2's i have a couple of items that might help or not help in this field for tunning purposes

S-ITC which is outdate an i think the highest timing you can go with it is 17'degrees advanced

Old school blue screen S-AFC

HKS 272 exhaust cam...



note** this is on stock ecu,springs,retainers,rocker arms


now the hks cam i just threw in there only if you guys think it would help out the HP with having the BC intake cam.. if not i wont do it also id like to know if the hks cams needs springs an retainers with the stock rev limit of 7,500k


i think the s-itc on a dyno might help out the tune a bit but its so outdated who knows..

s-afc will help on idle an tuning but *** if stock ECU with timing advanced all the way on zylene an 93 octane would suffice my apetite i rather try that..


let me know what you guys think...

comeon!!! someone that has had cams or has experience with this.. some help would be appreciated

payu

I recently Installed BC Stage 3 and SR combo and find out that I hit the fuel cut too fast on 2nd gear so i decided to get a custom ecu tuned with a 8,000 fuel cut. You will get more all arround power with stock ecu with 21deg advance with 93 octane gasoline and you can tune the AFR with the S-AFC at least thats what I did before the custom ecu.....
By the way the best ET without cams was 14.39@93.8 and with cams and custom ecu 13.82@98.20

Hey Payu what was done to your motor inernally beside those cams and s/r kit if any?

STRATTON

id say advance the timing to 19 run 93, i dont know if the hks cam will work, only way is to dyno and find out.

what are the other supporting bolt ons ?

ive got
pop charger,headers,greddy exhuast on stock b13 piping an cat,no egr,UR 2 set,fidanza 9 lbs flywheel

oh yea an solid mounts

I was under the impression that when you've added "parts" it's better power wise to not run so much timing??? Did I say that right??

STRATTON

ahh 17 degree's is fine, so is 19 in my book.

only reason u should run 15 degree's is if u have a jwt ecu, there maps etc are based on 15 degree's timing.

HKS, ask Danilo he was running some BC cams on his b13 also a good person to ask is Gio if you know him.

HkSBlueBird4u

if i ever see him ill ask him

HKS has a few different 272 grinds. they have a 272 12.0mm lift cam and a 12.5mm lift cam. which one do you have.

HkSBlueBird4u

12.0mm

i wondered in the bc intake cam with cam gear advanced 2 degrees would work nicely on 272 hks exhuast cam with stock cam gear.
on stock 7500rpm rev lmit

The JWT ECU program for S5/C2/C3 requires 25 degrees base timing, correct?
