Re: Thread for those of us who tune our own cars
Changed the IAC to a fresh OEM ford unit and no change. Has to be something with the tune. If I unplug the IAC while its doing it, the car dies. So its flowing too much air through it. I smoke tested it and couldn't find any vacuum leaks.
MAF readings are really steady, so I don't think its that because air fuel is dead on. I did just learn that you have to change all of the voltage comp and pressure adjustment tables in the fuel injector data. Noticed my timing is jumping up to 30 when it idles like that, so I'm capping low load and low rpm timing to 5. Woooahhh! Capping the timing under 1.5k and .2 load fixed the issue. I also played with some of the dashpot and ISC functions to get it to drop to idle like a rock.

Congrats 828, sounds like you are really making progress on the 'ol learning curve

Re: Thread for those of us who tune our own cars
I think so! I've come a long way so far.

Re: Thread for those of us who tune our own cars
Good job on fixing the idle issues.
I'm going to start tuning my new 5.3 BB/S tonight. I started it up yesterday and it wouldn't run without feathering the gas on the old tune. I updated the displacement and will see how it runs. I forgot I changed to big Comp Cams so I hope I'm not battling that too much.

Re: Thread for those of us who tune our own cars
Did a quick test. Adjusted displacement and set idle to 950. Idled pretty well.
No need to tap the throttle or anything crazy. I'm sure I will have to do something when I lower it back down.

What is the most timing I should run on e85? I've got it at 19 above 5k and 20 below. Car runs really strong now actually get an adrenaline rush again

also you have knock sensors so log knock and add timing slowly tilll you see knock or it stops getting faster. i would think 21*or so would be ok. but monitor knock!

Re: Thread for those of us who tune our own cars
I shut the knock sensors off. They get to many false knock readings. When I ran e85 NA my tuner had to do the same thing.
I'm decreasing timing with rpm because I'm scared of how much power its making now with the stock bottom end at 115k miles. It dynod at 490 with 16 degrees of timing. Its got to be about 525 or so now. I'll put it at an even 20 and see what happens. Its roasting my 325 drag radials now from a roll with the e85 tune. Anyone boosted with e85 and doing their own tuning? It likes to run a little lean. At low 11s on the wideband it is choppy, but likes to be at about 12. I just changed the stoich value, added timing, and adjusted the base fuel table. I don't really want to mess with the MTF since its solid.

Re: Thread for those of us who tune our own cars
You dont touch the mtf if you just changed fuels it dosnt care if your e85 or meth or gas its just reading airflow. If its good then its good!

Re: Thread for those of us who tune our own cars
with the high compression aluminator and 15 psi we peaked at 19 degrees timing on E85. I didnt discuss in depth with my tuner but at 19 we beat my power goal so we stopped there, no need to lean on it too hard. It sounded like there was a few degrees to go still had we needed it.

Re: Thread for those of us who tune our own cars
Interesting info I found on running higher octane fuels and the combustion process.

Re: Thread for those of us who tune our own cars
good post... the slower moving flame front is why if you run high octane fuel in something designed for low octane you can get an incomplete burn that results in carbon buildup in the cylinder over time. Eventually itll raise compression a bit and then when you try to go back to low octane itll ping.

Re: Thread for those of us who tune our own cars
Latest tuning info to share:
The importance of the fuel pump voltage table. After the new walbro 465 fuel pump my table was way off, causing pressure 20psi spikes that could be seen by datalogging the pressure drop across the injectors, causing momentarily rich conditions and hesitation. The 340 pump I ran needed 13.5 volts up top but this walbro is only seeing 8.6 volts. I used a histogram data logging pressure drop across the injectors, actual fuel pump voltage, and fuel pump flow to populate the table. Next is to clip the pressure sensor transfer function. You want to clip it something close to the fuel pressure you want and then add your max boost. Many say to default to 60. The purpose of this is to keep the pcm from seeing random spikes and making drastic adjustments. It is located in the returnless fuel pump section in Advantage.

Re: Thread for those of us who tune our own cars
Results are in from my e85 tune. Hit about 8.5lbs of boost vs the 9lbs it saw on the 91 oct run below it. 50hp bump. 17 degrees of timing to 23 degrees.

Re: Thread for those of us who tune our own cars
Is that 17* timing max on 91 ans 23* max on e85?
are u raping up spark or just locking in 17/23 on the hit?

Re: Thread for those of us who tune our own cars
Increased it with rpm. Here is my BLK table.

Re: Thread for those of us who tune our own cars
Hey guys quick question.
How the hell do I shut off the knock sensors? I thought I did it but started the car and still getting codes for them. Such a big learning curve here

Re: Thread for those of us who tune our own cars
You have to deactivate the code to keep the light off.

There is a spot where it says knock sensor retard. And then it shows the degrees of timing they are allowed to pull based on load I think. I just zerod them all out where i didnt want them doing anything and I didn't have to mess with the codes. I did it this way so they can still adjust timing during cruise if knock isn't detected but they don't do anything for wot.

Re: Thread for those of us who tune our own cars
Any tips for tuning idle on a car with stage 3 comp cams?
The car runs but it won't idle. STFT's are between .98 and 1.02 so the MAF transfer is good.

Won't idle as in it starts but dies? Flow more air through the IAC valve.
