I'm new to the tuning scene and after watching a lot of videos on tuning in tuner studio i have a decent understanding of the features and options of the program but when i go to tuning my mustang i get to a good spot then make things all worse, like yesterday while tuning i might have added too much fuel to the ve tables because the car died wouldn't start after that. After checking for fuel, spark and compression i found out that i fouled all my sparkplugs from running too rich lol crazy day.
what I'm pretty much asking is, is there anyone who might have a decent tune for a 5.0 vortech supercharged making 4lbs of boost, gt40 heads, tfs1 cam and 42lb injectors. id like to compare it to my tune so i can see what I'm doing wrong and learn more about tuning so i can get back on the road thanks!
I do not, but I have a few questions for you. What made you keep adding fuel?
What AFR were you trying to achieve at idle?
What wideband are you running?
What type of megasquirt are you running/firmware version.
Do you have the paid version of tuner studio / TS Ultra
Do you have the paid version of megalog viewer? MLVHD?
Well kudos for getting a car to run at 18-20 afr that's a feat all in itself.... but I have to ask then, what is wrong with either the wideband or your calibration for it to foul the plugs but read stoic? Fouling the plugs above 13afr is near impossible, something is amiss.
This is a boosted car so i have to ask why do your tables AFR,VE stop at 100kpa?? boost begins at 100kpa and goes up from there. 10psi is about 170kpa.
both AFR and VE tables should have enough resolution to go all the way to your target KPA.
Now lets talk about the timing table, it looks scary and choppy... the timing numbers you have in will certainly blow the engine up in boost. 200kpa is 15 PSI of boost, i doubt you will be running 24* of timing up this high on pump gas unless you want to scatter parts everywhere.
Here are some examples of tables from a fully tuned car driven on a daily basis, one thing you have to remember is you cannot simply copy the tables or tunes from someone else, alot of settings in the software effect the outcome of the actual fueling of the car.
