2013 Mustang 5.0
On3 turbo kit 80mm single
1050 id injectors
boss 302 intake
grams 90mm tb
stock engine
I have only tuned a few fords, but I got everything figured out except for it stalling...
I have a 2021 camaro SS with a completely stock engine, LT4 blower and LT4 fuel system. Does the leading and trailing edge angle need set to the LT4 setting or do they need left to the LT1 settings...
124800 The timing doesn't seem to drop in this instance but it does seem like it starts to go into DFCO then the fuel trims max. I just don't understand why.
I have disabled DFCO and CFCO but it didn't have any effect. I haven't logged fuel trim cell but maybe I will. Even if I can prove it is related to a certain fuel trim cell I am not sure how to go...
Is this a normal characteristic or any idea what is going on here? Cruising 50mph or so and depress clutch and go into neutral, Engine surges and sometimes stalls. I happened to notice when this is...
I see where your going with this. 628 kpa is about 90 psi So it will never feasibly be in those cells. I'm gonna dig into this car a little and see if I can find exactly what injectors are in it. Get...
If it is not halved then the values are maxed above 127 lb/hr from the 628 cell up.
Also I have tried repolling with no luck. I ended up adding the channel Intake manifold absolute pressure and...
Thank you! Any clue why the Manifold absolute pressure PID doesn't work in the scanner??
This is a friend of mines 2014 Camaro SS. He bought it used from auction with no history. Took it to a local dyno to see what it makes and it made 520 hp which he thought is low being that it is a...
Ford performance intake, stock injectors, BBK twin 62mm throttle body. It is NA.
Here is a driving log with it happening also, could it be something torque related limiting it? I didnt mess with the torque table at all since it is almost stock.123649
Can anyone make any sense of the random timing dip that is occuring in this log at -2750?? Intake and catless exhaust only. I have other logs with it happening at 3-4000 also. Seems like some kind of...
Camaro ZL1 Built LSA, ported stock blower, 2.45 upper/9.17 lower, btr stage 3 cam, ID 1300 injectors, 105 throttle body, BR9ES plugs (occasionally runs 200 shot). Tune is in Maf only right now. I...
Figured it out. I was logging intake manifold absolute pressure and found out I need to log manifold absolute pressure hi res to get the proper reading.
I am using the map sensor breakout from the maf 3 wire map to the 4wire tmap sensor. I have the Lt4 tmap sensor in the rear port of the Lt4 blower. Set to NA-TIAP, Linear is set to 425kpa, offset is...
I got the timing to be much more stable but now the IAC still is over reacting. Do I use the proportional airflow high and low and reduce the values to slow it down?? From my understanding, as the...
99 5.3 stock with 228/230 112 + 4 lsa cam. My idle is surging pretty bad until the truck goes into closed loop then it seems to get much better. It is in SD right now as im just trying to dial in my...
I found out the wrong style of o2 sensors were being used! Now I am getting readings and can start dialing in the tune. I guess the segments that were there are actually correct or atleast correct...
Okay I am going to attempt segment swapping it. I found a file with the 4l60e trans its equipped with. Do i swap over all the segments that have a different number and leave the ones that match...
Yes it is licensed. I made a few changes and reflashed it. It does run but not well. I still have to tune it but it backfires out the exhaust and my primary o2 readings stay at .447 for both banks. I...
Sooo is this thing a brick or can it be segment swapped or is any some other solution??
Im working with a swap vehicle. 5.3/4l60e out of what I believe was a 1999 silverado. The wiring was all complete and pcm installed when I got the vehicle. Under the Calibration details it comes up...
Do you have a log of it surging??
I don't have my laptop on me right now but can post the calibration file up later. Thanks
