Sure Let Me Dig One Off My Laptop At Home And Ill Post It Up

 

This sounds like a pretty cool idea actually. I too am interested in seeing the log file!

Ok Good! When I Get Home Tonight Ill Try And Post Some Screen Shots Of The Log File I Got

This Weekend (mabye Sat Or Sunday) Ill Do Another "test Run" And Log The Whole Thing

The Only Issue I've Been Having Thus Far Is Dealing With The Double Enrichment Of Having A Pre Maf Spray And A Pe Modifer Set To Do The Enrihment...

Ovbiously The Simple Solution Here It To Just Move The Nozzle To A Post Maf Locaton

In Anycase I Have A Log At Home That Shows This Method Working ... Ill E-mail It Ot Anyone Who Wants Ot See It And Ill Post Up Screen Shots Tonight For The Rest

 

I'm down for the email option!

 

Pm Me Your E-mail And Ill Send Over The Log I Have

 

Done.

 

Screen Shots... After Reviewing The Data Some More I Have Found That There Is Less Than A 1\2 Seccond Delay For The Timeing To Be Pulled

This Is No Bige Deal Though Because All You Would Have To Do Is... Set Your Timeing Pull To Roll In A Few Hundred Rpms Before Your N20 Shot ... Duh!

Anaway Due To Cops And Rain This Log File Sucks .. I Only Have A Few Breif Pulls So Im Gonna Post Up What I Got And Make A Nice Long 0-130 Pull This Weekend

 

Also Please Take Special Notice To The Time Between These 2 Frames It Is All Of .6 Secconds!!!!

 

Should zoom on those screenies more so you can see more detail in the time, sure looks like they're zoomed out pretty far...

BTW, what is wrong with your wideband data? Doesn't look right at all to me.

 

Good news is... it seems like it does work...

 

Wide Band Is Piped Through My Egr So Without My Cust Pid Its Just Crap Data
You Can Save The Image And Zoom In On It To See It Closer

What I Dont Like About This File Is That The Pull Was From A Roll With A 4000+ Stall Converter Is When You Look At The Rpms You Do See A Few Hundred Slip By ... This To Me Is Not So Much Of A Big Deal Because If You Look At The Time You Realise Just How Loose The Stall Must Be And Accordingly How Small Reaction Time The Computer Really Has (1\2 Seccond)

Eventhough, In The Name Of Perfection (even When Illrevelant) You Can Just Back Up Your Iat Retard Table A Few Hundred Rpms To Offset The Ammount Of Time It Takes For The Computer To React To Even This Extream Condition

 

I wasn't talking about the image's zoom, I was referring to the zoom within the scanner... but doesn't matter much.

The stall does kinda suck for data collection... a nice 3rd gear pull from about 2500RPM would rock though for displaying this data!

How Do I Adjust Zoom?

Also I'll Be Logging This Weekend And Ill Shoot For A 2nd And 3rd Gear Pull

 

JP, I was talking about the Interface and how you said it worked, that was what I was calling BS on, as the info you presented is incorrect. That is not how it works in any shape or form.

Now as for your timing pull, well I still haven't really had time to look at at it closely and never called BS on it. Now like I said before, if you can get the delay part of it figured out, maybe it would be a viable option. Check your dyno sheet, your max TQ spike is likely included in your ½ second delay. Max tq is where we want max timing pull. The HPT timing pull method in my personal web works flawlessly and has absolutely no delay or lag and can be set up with a timing curve which can be very handy for those of us going big. Hey, if this ends up being a good option, I would love to include it with my other tuning options in my site. Most all of the resistor trigering tricks are on there already, but most of them are less than desirable to use for various reasons. Anyway, don't always take my input as personal jabs, as I talk this same way in all my posts, it's just my style to get to the point with no candy coating, and yes some don't like that. I have no vendetta towards anyone.

Ok 3 Points...

1: I Think Your Missing The Fact That The Change In Temp From The Iat Happens When You Arm The N20 System Not When You Spray This Means The System Has Time To React.. Even If For Some Reason It Didnt; Then You Could Still Just Write A Tune To Start Pulling Timeing A Few Hundred Rpms Before You Spray And Tihs Will Give It Ample Time To React... As Of Now My Shot Is Set To Spray At 4000 Rpm, Im Gonna Start Pulling Timeing At 3200 Rpms (using The Iat Spark Modifer, Multpulier Table)

2: I Know Without A Doubt The The Interface Basically Grounds Out The Iat Sensor.. I May Be Oversimplifing Things Because Yes I Do Realise The Interface Is A Complex Circuit Board But This Does Not Change The Point That There Is Only 1 Way To Modify The Iat Signal Going To The Pcm... If Im Wrong I Invite You To Explain How You Believe The Hsw Interface Is Achieveing The 158 Deg Iat Signal Which It Uses To Pull Timeing Through The Pcm..

3: Im Happy To See We Can Keep Things Civil, Im Here To Talk And To Learn.. Fighiting Sometimes Happens But Is Not Desired....

 

Anayway Tommrow Or Monday Im Gonaa Have Time For Some Pulls .. Ill Keep You All Posted On My Progress

 

Update: I Adjusted My Timeing Pull And It Looks Great (ill Post Later) Im Still Haveing Issues With The Enrichment

As Of Now It Falls Quickly To The Desired Afr But Then Rebounds Up To A Afr That Would Be Used If I Wasnt Useing The Modifer Table....

Im Gonna Look Into This More, But To Say The Least This Looks Promsinging

 

Got It!

Like I Originally Eluded To The Ground For The Iat Will Fluctuate A Little So If You Dont Use Both Extreams Of The Tables When Makeing Fueling And Timeing Adjustments You May Not Be Commanding The Right Ammount Of Spark And Fuel

This Is Exactly What Happened Im My Last Pull As At Idle My Iat Was -38 But Upon Going Wot My Iat Was Pinned At 258... Although This Seems Crazy You Have To Remember That -40 Is Just A Small Resistance Value Away From The Other Extream Of 258 So Any Fluctuation In System Voltage Could Cause This

Simply Put: You Need To Use The Upper And Lower Ends Of The Tables

 

Ok Its Done...log And All!!!!

YOU CANT REALLY MAKE ANY SENSE OF MY FUELING AS I AM PIPEING IT THROUGH THE EGR SO UNLESS YOU HAVE THE SAME CUST PID AS ME IT WONT LOOK RIGHT BUT I THINK YOU CAN GET THE IDEA


*** IMPORTANT NOTES***

MAKE SURE YOU USE THE UPPER AND LOWER END OF BOTH TABLES
I CHOSE TO USE ANY VALUES OVER 200 AND UNDER 14 DEG AS I KNOW I WILL NEVER USE THESE CELLS....

THE ONLY 2 IAT TEMPS I RECOEDED WHILE ACTIVATING THE N20 STSTEM WERE -38 AND +258 THESE TEMPS ARE ALMOST IDENTICAL (RESTISANCE WISE SO A SMALL FLUCTATION IN COMPUTER VOLTAGE CAN CAUSE THIS)


ALSO MAKKE SURE TO PHASE IN THE TIMEING PULL ABOUT 600-800 RPMS BEFORE YOU SPRAY.. THE COMPUTER DOES TAKE A LITTLE TIME TO REACT

IF YOU LOOK AT MY LOG YOU CAN SEE HOW NICELY THE TIMEING CURVE AND MY TPS INTERSECT .. THE IDEA HERE IS THAT YOU BEGIN TO PULL TIMEING A FRACTION OF A SECCOND BEFORE YOU GO WOT

ALSO I USED A VALUE FOR MY PE ADDER TABLE THAT I KNEW OFF HAND WOULD GIVE ME A 11.O AFR I DID THIS BECAUSE I KNEW MY DRY KIT WOULD GIVE ME ENOUGH MAF READING TO KEEP IT APPROXMATELY THE SAME..

IE: COMMANF 12.8 THEN ID HAVE 12.8 ON SPRAY (BAD)

IF YOUR SPRAYING POST MAF THEN YOU WILL PROBALLY NEED TO COMMAND FOR SOMETHING IN THE LOW 10'S (DEPENDING ON SHOT SIZE) AND THE N20 WILL BRING IT BACK IN CHECK .. SIPLY PUT COMMANDING FOR 11.XX WILL NOT GET YOU 11.XX IF YOU SPRAY POST MAF


-ENJOY!

 

Screen Shots Added, You Can See The Fueling On The Screen Shots Since I Took Them Form My Laptop
