HP Tuners Tuning help Hello guys, I was hoping you guys could take a look at my log files and tune file. I noticed that around town driving I am sometimes logging 40 degrees of Spark and was hoping a more experienced tuner could tell me if something is going on, if thats a safe number or not. Everything I understand is the spark should be around 26 degrees give or take.
Thank you in advance.
Thank you in advance.
I don't have my laptop right now, but I'll say I don't find that shocking. It's a little higher than I go, but I regularly have high timing in cruise areas.
Did you have this tuned by someone, or buy it as it is or?
How about some more info on what the combo is and what it's in?
It sounds like you're reading on peak timing, or WOT timing.

I have had the car tuned on a dyno for max power but not tuned for just daily street driving, although I don’t drive it much, lol. But to be honest, I’m not sure about the tune, not saying anything bad about the tuner, but more that I’m just unimpressed with the numbers I got from the dyno. I know I have a combination that should make at least 100 more ho than what it dynoed at.
The engine is an LS2 block with flat top pistons and a Texas Speed Cam 231/242 .629/615" 112 LSA+4. It has stock LS3 heads on it with .660 springs and bronze trunnions. Also has LSXR intake manifold, 102mm TB, 255lph walbro fuel pump, 36lb injectors but they go to 42lb @60psi. Using a 4l80e transmission with 3200 stall.

that's normal timing/spark advance for part-throttle normal driving... some are even in the low 50's for part-throttle normal driving... so, no issue... at WOT it would be lower, down in the low 20's....

I obviously don't know what it made, but I wouldn't expect anything over say 415-420 out of it, maybe a little more.
Every Dyno is different and every day of weather is different, but a Dyno is just a measurement.

Hey guys,
So I was doing some logging the other day and noticed my o2 sensors were having large differences in readings. So in my diagnosing I noticed that the #2 cylinder hadn't been running. The spark plug looked brand new with only some smoot near the electrode. Put a noid light on the injector and apparently the wiring had been cut. So I wired it back together and fires fine. But......it started smoking from the exhaust immediately. Its a white smoke that smells like gas. I disconnected the injector again but that didn't stop the smoke. I drove a few miles thinking the rings may have needed to seat again but still smokes. I am attaching some log files of the drive. Also, the o2 sensors are still having the same differentiation in readings. I also pulled the codes and noticed a few interesting ones, p0103, p0200. Can anybody give me some suggestions on solutions or more diagnosing?

If it has narrowband o2 sensors they're supposed to swing lean to rich or high to low. It's just how they work at anything besides wot.
P0103 is a maf code, tuner may have it speed density tuned.
P0200 is a problem with the injector circuit.
No clue on it smoking. Is it smoking like alot, what color is it, and what does it smell like? Did fixing the injector wiring fix the misfire?
edit I see you said it's white and smells like gas. Is it running rough? maybe unbolt the fuel rails, pull the injectors and rails up from the intake, and switch the key on with out starting and see if any injectors spray fuel. DONT DO THIS IF YOUR INJECTORS DONT HAVE RETAINING CLIPS HOLDING THEM TO THE RAILS.
