While cruising between 55-65mph or more (5th or 6th gear), it is okay for the A/f to be in the 13 - 14 range. The idea of cruising is to save gas and you don't want a ton of fuel while cruising or the car will stutter, bog, etc.

 

but its in the high 14's under decent rpm's and throttle, I can feel the power coming on and the wideband is way lean, I guess its just before wot conditions..??...

 

why dont you go see Zombie, your getting some half-assed info here and your not up to speed yet. you will learn alot faster and save your motor going to an experienced tuner to get you going.

 

I cant spend money for a tune, I wouldnt have bought hptuners and a wideband if so, I would have just gone and done a dyno tune down at a&a in cali, I just need to make my wideband happy and get rid of the kr, yeah its complicated but at the same time basic, I'm just needing some better understanding on the tables that need tweaking, I got some high 11's on the wideband just a little while ago under wot but still got some kr, I'm deciphering the logs right now, gotta do some more tweaks and try again....

 

Half-assed information? Hahahaa...thank you. At least I am trying to help him and I'm fairly experienced with tuning. As for you not helping yet degrading others...that is another story.

Assassin, if you can follow the information I posted earlier regarding KR and taking it out on the specific table, that will help. You're also welcome to give me a call.

 

Not degrading anybody, just saying he is not getting nearly enough info in this thread to make things work.

This for example.. Across the board? Why the heck would you pull timing at all the points in the table he can never get into boost? If he pulls 5 across the board thats what will happen and he will be making the car a dog at part throttle. Also 5 degrees is not nearly enough pulled timing in the areas he needs it pulled. How bout the low octane table? How bout adjusting the when the car goes into pe? How about explaining how to adjust pe? How about timing vs IAT, and the all the various other things he needs to do to keep his car from either A, going boom, or B, running very sub par.

If your gonna help, give all the details I guess is my point. Perhaps saying half-assed wasn't very nice. Wasn't directed directly at you, just the thread as a whole.

 

Thank you for the explanation. Like you stated, he's a beginner and I recognized that immediately. I was simply giving him a starting point to get his car running correct...and without KR. Yes, there are many other adjustment points but he obviously wants to drive the car and "tune" it himself. I'm not sure he even knew what I've previously mentioned with regard to tuning the knock out. At least he is trying...and he has to start some place.

A difference of 5* at part throttle makes little difference and he can always put timing back in. Give him a chance to learn and don't take his pencil away. His car will not blow up missing a few degrees of timing. It would have possibly blown had he kept driving it on a stock tune with 9* of KR...and nobody, in the least bit, trying to help.

Again, thanks for addressing the thread and give him some tips.

 

Assassin, brah, if you no afford $200 tune, how you buy new engine when dis one pops? **** brah, havent heard from you in long time, Vegas now huh? Will be in AZ in a couple months, we gotta hook up.
No offense to NOSjohn, but I would take Blackbirds advice, and Zombies offer before you have to buy a new shortblock. And, for future reference, I am sure Zombie pm'd you amount he asks for tuning help, and that doesnt need to be posted in public forum.
Now, I am tracking with what BB was saying. Only need to pull timing off PE areas primarily, some at PT, I also adjust vs IAT (Advance and fueling), and the list goes on. To do it w/o reference points, or experience is a bitch. Been doing Larry's STS (the discharge pipe blowing turbo'd SS on island) and its slowly making progress, a little timing, a little PE, a little IAT modifier etc.. Good luck and dont blow your **** up.

 

yeah, I thought I had a good ideaw from the get go, drop the **** out of the timing and up the fuel, basic, then get rid of kr and up timing where I can with making the wideband and the knock censors happy, I thought there was alot more to it but I guess not, I'm not normally spooked on tuneing but I want to be really safe w/ this boosted stock internals....
CAT3, where you gonna be in AZ?, december time?, need to take some time for a drive.. btw, did you guys refrence the wastegate to the pressure side before the throttle plate on the ss

 

here is my old timing table for 11 psi of boost on 91. That should help get you started, this table is far from optimal but it's pretty safe and I made 500 rwhp on it. You might need to lower the timing a bit in the lower rpm ranges if you spool faster than me.

Wow, this tuning info is way off. This looks to be a disaster waiting to happen. With a turbo vehicle I would have PE starting at about 35-50% throttle position. Take out timing under boost conditions and add in non boost areas were you can. With the VE table correct a 1.24 multiplication on power enrichment would get you around 11.5:1 for AFR, that is if the fuel system is working properly and supplying the proper amount of fuel. Make sure to take out some timing at the higher IAT's in the IAT correection tables.

 

ahh, the iat correction table, I just had a look and it dosent start taking out timing till 104 right now, my iat's are between 75 and 91 so far, I'll just add on and move that table over more...

 

I agree. I brought in PE alot sooner, since you can get into boost at part-throttle.

 

I also droped the pe down to 30% @ 2400, 20% @ 2800 rpm and up

 

Anyone know the answer to this? I've got a boosted C5 and am wondering the same thing. It looks like I'm running high 13's to low 14's during part-throttle. Will this hurt the engine?

 

Thats correct. When in closed loop. Part-throttle, no boost. you want your AFR around 14.7

 

whoa yes, dropping the tp% pe rpm table helped big time, its going fat just before boost hits, I like it, I'm still working with the timing though, I think I'm getting thrown off by some false knock when I go into the next gear, I'll give you guys an update if I can get things running smooth

 

Keep working on it, you're getting there and gaining knowledge while you're at it.
