Spraying A Dry Shot.. Dont Really Wanna Use A Timing Adjustment Device... I Need To Pull Approx 6 Deg For My 150 Shot


I Mas Thinking To Juust Go Into My Main Spark Advance Tables For High And Low Octane Fuel And -6 Deg Of Timeing For All Values Over 4000? Rpms

(4000 Is Where I Start To Spray)

Is There A Better Way Of Doing This?

If you do that, it will be a dog on the motor

A custom operating system could be used to pull the 6 degrees when you arm your nitrous system, only thing you have to buy is a 10 dollar relay

I Would Go The Cos-5 Route But Im Currently A Hpt Customer.... I Was Using The Hsw Interface For Timeing Pull But To Pull 6 Deg With It You Have To Modify Your Iat Tables.. When You Do This And The Car Has Been Sitting Your Iat Sensor Becomes Heatsoaked And You Run Like **** Anayways

My Last Option Im Looking Into Is To Make A Relay Mod For The Ect Sensor And Just Modify My Tables To Pull 6 Deg Of Timeing At Whatever Engine Temp I Choose


Also I May Still Mod My Iat With A Resistor\ Relay As The Interface Only Pulled A Max Of 156 Deg And It Was Irratic At Times If I Used A Resistor I Could Pull A -40 Temp Which Would Allow For This Mod To Work Without Messing Up My Na Tune

Just Out Of Curosity How Much Would You Charge To Convert My Current Tune To Cos 5.. Im Spraying Using A Nitro Have Halo And My Afr Is Good As Is So Really All I Need Is A Good Way To Pull Timeing

my car doesnt feel much different on motor with 5 degrees of timing pulled with TR6 plugs. I wonder what the HP difference really is

i was told like 10 hp...besides if im really raceing im gonna be spraying..

i dont like the idea if relayed **** because if that realy fails your fucked!... i just pulled my hsw interface.. as good as they make it out to be i has numberous runs where my iat's were bounding all arround on a soidered wire.. when your pushing this much power there is no room for error..

Th reason we use a relay like we do, if the relay fails, not only will it not change your tune, it also will not arm your nitrous so it wont hurt anything

Give us a call if you want to talk it all over, nothing is impossible

Make a note of the cells you hit in the high octane table
n/a vs when you're on spray.

They'll probably be different...assuming you're spraying
before the maf.

I would pull a little timing right before the rpm you spray
at just to be safe.
