thanks for the info

 

the last revision i got was close to 2 years ago. i spoke with angela who transferred me to bill. i assume it's the same bill. after that i went on to try a couple diff tuners tunes.

 

here is a video and yes i used my cell phone. not the greatest but if you watch the tach ( select 720 in settings) you can see the needle move. i know i need to open the ae program and look things over. i was talking to brad yesterday. i don't have a break out box but do have a valve cover harness and a solder in pig tail connector i keep just in case. i will sacrifice them to make a sort of break out box at the valve cover. i can mate the harness to 4 switches to shut each inj down and watch commanded fuel. this would atleast let me know if it's actually inj's or not. i helped my niece move yesterday so drove the truck with a light little car trailer, only 3k lbs. it was 55* ambient, had rained for 1.5 days, so cloud cover all day. at 70 mph, 2150/2200 rpm, 10 mph gently side breeze, 600* ish egt's, holding 5 psi with cruise set on flat ground ( hwy) holding 195* coolant according to my auto meter gauge. pull to a stop and this is the funny idle i have been referring too. switch from stock mode to tow performance and no change in idle. switch from stock to heavy tow and idle cleans up 25-50%. didn't think it would do it with such a light load on flat ground but only did it once. could not get it to do it again in the return trip home. it's just bizarre. again i need to connect with ae and verify a few things. i did try turning the wheel while it was doing it and that had no effect on it. it sounds and feels just an air idle circuit, on a gas engine, hunting and adjusting surging the idle. i will check idle validation as well when connected. i know the video doesn't tell much but you can kind of tell what i am talking about. i would to think that this is just what single shots do in sd trucks but maybe it is.

Yep, pretty much what mine sounded like before I went at it like a tweaker with a fresh batch. I'm still fighting it but it has improved for sure. What's that higher-pitched chirp squalling kind of noise I'm hearing under all the knocking? Almost kind of sounds like a water pump chirp.

 

i hope it's not the water pump as it only has 14k miles on it. that is a good question though as i cannot hear it inside the truck. i will have to go investigate that now. could be the alt as i know that bearing sounds a little dry.

 

Do you hear it also or am I just losing my mind? Been chasing the Knock Dragon for way to long.

 

i do not hear it while sitting in the truck but when i turn the volume up on the video it did hear it. so i went out and pulled the belt ( after your post) and spun all the pulley's. the alt is original and was dry......sounded like rolling a bowling ball down a concrete drive way. as i am heading out on a trip to the dunes this week i went ahead and replaced that. upon testing the voltage at the battery before and after, i discovered i have two out of 3 volt meters that needed to be thrown away! one was showing 18.9 v's at the battery and the other 5volts. the 3rd one and the cheapest one shows what my snap on scanner shows 14.2volts at idle. that craftsman volt meter was a very nice volt meter, don't know what happened to it either.

so after a run into town to get 30 gals of e85 for my sand rail, i decided to pull out the snap on scanner and just view some data. this is an older snap on scanner and cannot be updated beyond 2005. i have the powerstroke key for it so does all i have needed to with the truck. the retired mechanic that was selling it knew it was no use to current mechanics. he took very good care of it and had several keys and cards for it. i gave $100 for it and keep it in the truck, won't be horribly upset if it was damaged but i do like it. i snapped a few pics of the data stream while at operating temp ( 185* according to the autometer gauge) , at idle and iat was reading 59*. brian at jelibuilt stated to me ( per a phone call) that he targets 620 icp and that i should be 10% ipr. this was all per a call asking for a revision for my " custom tunes" for my e99 as the idle quality can get poor at times. it's not all the time though and does change with tune but does not go away. i was speaking with brad about sacrificing one of my spare valve cover harness's and a solder on pig tale to make a sort of break out box to test the inj's.any suggestions as to what switch's to use for such a test? just want to shut each inj down to monitor mfdes. i will do this but not until i get back from the trip. i will also data log through ae or down load another program. so one interesting thing was that oil temps were 5* cooler at idle compared to the autometer gauge. brad was telling me that every time he has experienced a poor idle he had noticed his pw was below 1.5 depending. i was not experiencing the poor idle/lopey idle while looking at the data. wasn't a great idle but wasn't the poor idle i have been chasing.

php high idle


jelibuilt stock tune


jelibuilt high idle


jelibuilt daily driver


jelibuilt heavy tow


again these are all at operating temp, at idle. just thought it was interesting to see the changes per individual tune per tuner.

 

the rpm wander is about 25 rpm in the better idling tunes. the others are about an 75 rpm wander.

 

You may need to crop and reload those pics or something, don't know I'm not very useful in the tech department. Trying to view them on my Android phone at least they are to small and can't zoom in.

 

i just noticed that. supposed to direct link it to postimage and expand but that i not working. if i select open link in new tab they go full sized. let me try this another way.

The 2 things that jump up and slap me in the face are the IPR DC% on the high side for hot idle, and the significant difference between jellybuilt and PHP for your mass fuel desired. I know when mine sounds the worst at idle my MASFD is high. 9 and below sound ok get in the 10,12,15 range and I start loosing my mind.

 

when i swapped all the parts , 205/30 inj's, t4 up pipes, bgsxe366 and adrenaline hpop, i bought a motor craft ipr. i bought it off ebay, said motocraft and showed up in a motocraft box. i have had no issues that i know of but i suppose that is possible. i just find it funny that every tune commands diff perimeters at operating temp idle. it even effects idle rpm as you can see in the pics. again, i know that's not a data log and i will work on that. it was a little unsettling to have brian from jelibuilt simply tell me it's pointless to write revisions, i need live tuning and there's something wrong with my motor. he said that based on my statement of i think ipr is at 14%. i was simply asking him if he could make a revision to turn pw up a tad but i will run some tests to verify a few things before i look for another avenue. i have the dcp21 pcm but really don't want to swap out the e99. i do pre fer jelibuilts tunes as the tps isn't overly sensitive as all the others. his tunes are the best on tip in for towing, now just need a little better idle. apparently now most don't want to write tunes for e99 truck now. i would be more than happy with a live tune if i could find someone close to home as in 4 surrounding states lol i will have to see if there is anyone in ft worth/dallas area before my next trip down there, that is after i check a few other things.

what rpm does your truck idle at?

 

the php heavy tow tune def has the best idle over all the tunes.

 

i have even considered swapping back out to split shot injectors with larger tips and dropping down to the sxe 363 turbo. i don't need 35 psi boost to pull the hills i run. when controlling the throttle by foot i have never needed over 28 psi to maintain ground speed. based on sous's preliminary as well as two other posts i have read, i think this may be the way to get that crisp clean idle back and a little more of the bottom end i lost switching to the sxe366 trubo. the adrenaline hpop should do a better job supporting the split shot inj's vs the stock 15* e99 hpop.

 

btw, i would like to thank you for catching that chirping sound in the video. that would not have made a fun trip if that bearing in the alternator seized on the interstate towing my camper!!
