ECMlink learning to better adjust WOT logs

BrainSpilnerJR · Feb 9, 2020

Hey guys, sorry to for the new guy questioning. I'm self-teaching/educating myself, and learning the hard way is gonna happen regardless. I am on Speed Density. Just installed some FIC 750cc injectors on my GST/X. I did set idle quite well i think, and cruise probably is a little messy at the moment. I'm trying to better understand how to correctly calibrate the injectors at WOT. I did notice that I'm running extremely rich at WOT. I don't quite understand how to bring up that 9.x value to around a safer 11.1 AFR number. Car is running off of just the 17psi FP wastegate. I'd imagine this issue is quite a straight forward fix, but i haven't wrapped my head around things completely quite yet with this program. Here is what is done to the car, and lastly a log. Hopefully I've informative enough in this posting, and thank you to whomever can help.

There are multiple ways to do it. You could either reduce the ve in the ve table or you could change your global. If you ever wanted to reduce your ve, you would like at, for example, a wideband factor of -6% and reduce that corresponding ve cell by 6. To lean up the global, you would want to go more negative, or a higher negative number like -41 or something. The higher the number, the larger the ecu thinks the injector is and will reduce fuel throughout the tune. I'm only an amateur, but I would suggest changing your global and of course retuning idle as global will affect idle.

Im in the process of learning how to tune as well. Does anyone know of a video explaining and walking thru the WOT tuning process? Ive seen a few of Jafro's youtube videos and they are very helpful.

Not sure if scott laird has any on YouTube.
Search him on YouTube.

Ive seen his video but it was with SD, Im still on MAF. Would that be the same principle or would it be totally different?

He has one for MAF as well

Same thing except you'll be adjusting the MAF comp slider instead of VE table.

You have a CEL for knock sensor. I'd get that situated before doing anymore WOT pulls.
Go into your openloopmaxoct table in DirectAccess and change all the 10.x to your desired AFR.
You can use interpolate feature to smooth out your VE table.

Yo can increse from sd map
With wb factor % added or substract from ve case in that rpm range .
The Target is is get aol sorted at 100% eficciency if change suggest more than 100 you better need to change from global inj settings
A way to do this is do some math
In example
If you already have 100 ve and wb factor suggest 17%
Yo can do this
100*(17x100)*(your current injector size setting)=new global

100%117*1500=1282 new global setting
Also always check your duty cycle to know if you maxing out pump or have some issue
As advice a cheap ebay ebay pressure transducer to log pressure can help a lot
And remember always do the starting point with low timing until you sort the fuel target part then increase

For more knowledge you can hit kevin jewer he is very good man and friendly with advices also can do all for you a(remote tune services)sure you will be satisfied

Thank you gentlemen for the advice. I did figure out on my own last night about OpenLoopMaxOct Table, and set all of my 10.x values to 11.1. I did another pull this afternoon. The car is starting to feel better after that table adjustment. still have a odd feeling about my fuel and/or boost. I do have a 150psi transducer sitting in a box, as well as, a Ingersoll boost controller (3 port). You are correct i do need to install the fuel sensor to help with troubleshooting and monitoring. I got quite a few (-) negative number readings for WBFactor this time around. I'm curious about if I'm not running enough boost now. My InjDuty never peaked over 60%. I have yet to learn about the timing table stuff and making the correct adjustments. I do appreciate you guys for baring with me on the "new guy" questions.
