I took the values off of a stock ls7 maf and calculated the values at the frequencies given in the ls1 tables. Depending on how large the maf housing is the transfer function will change.
yes it adds to the base running airflow tables. the throttle follower is meant to increase the airflow when you let off the acclerator. Increasing the running the running airflow numbers also can...
I have two laptops with hptuners on it. Its all about your mpvi. You can only one mpvi per computer, but you can have a multiple computers with one mpvi. Just make sure you keep track of ure most...
you also have to change the injector offset vs volts vs map, short pulse adder, min injector pulse, and default injector pulse. there is a lot to, if you set up those tables correctly you should not...
I have heard that the 2011 and up ford stuff is encrypted, especially the superduty series.
Agreed, check for an air leak.
Yes the characteristics of the injector are extremely crucial, its the computers basis for determining how much fuel mass is needed. If these values are off, you are going to be chasing your tail...
you need to make sure that your offsets vs vacuum vs batt voltage, short pulse limit and adder and minimum injector pulse are changed to match the injectors as well. As long as you used the excel...
It sounds like you need to adjust the adaptive idle to compensate a little quicker, check and see what happens to your short term idle trims when this happens. What do your iac counts look like at...
I would call the injector company and get the voltage offset and short pulse data. You should not have to make changes to the VE when you change injectors. If you do then there is an error...
Dont ever move the throttle blade from the stock location, it messes with the car thinking that its idleing. Make sure the tps voltage is at most .65v. If you mess with the tps remember to do a...
Those injectors seem small for a 427, how much power are you making? Im using 60lbers on mine and they are at 80% duty cycle.
Heres the tune i use in my 427. It works perfectly for me, 650 rwhp/610rwtq.
After looking at the tune, you are going to have to do something about you IAC counts to get them lower. The best thing is to pull the TB off and drill out the hole. You want to get them in the 60...
If your car will not start then you may have to drill out the hole in the throttle blade or modify the tps sensor so that you can adjust it. If the throttle blade is open to far it messes with the...
The numbers are going to change, because the weather changes from day to day. You need to pick a day when the temperature is average not to hot and not to cold and log the raf table. After doing...
I have a question, I switched the coils from my 03 tahoe to my 01 camaro. The camaro is not stock, its got a pretty healthy 427, and spins considerably higher, should i change the spark dwell tables...
Dont forget to try to get your raf table inline, its going to be tough with a th400 because the computer is not going to know when you are in gear. Ive take WS6s advice before and it worked out very...
The follower isnt really gonig to affect that, because as soon as you take your foot off the gas this feature does nothing. The cracker is what your interested in. You should make so that as you...
Ok ill do that and see what happens. It turns out i have some other issues. Thanks if something else happens ill let you know.
how would i know they are hitting the targets? The average afr is about 14.63 but it seems to go more lean then rich.
Im running in open loop at idle because of all the overlap in the cam. No matter what I did I had a heater performance issue at idle. Ill take some of the pids out. What am I looking for I look at...
Im trying to get my closed loop tables in line. I have run the car in olsd for quite some time and ran great it just got to be a real pain to mess with the ve table every time the weather changed. ...
Im finally dialing in my running airflow numbers too because jeremy fomato just kept opening the blade and relying on the timing to do the job. I just never know what the stock position was on the...
