On a recent trip to/from Arizona, I noticed my SHO was pinging. Occurs when car under a load. Not sure if could have been bad gas (Chevron) or the desert heat (115). Another caveat here, AC was definitely blowing. I don't remember if I turned AC off to check. Engine temp was 190 degrees, 3/4 tank of gas, 1 only driver in car with 100 lbs of total cargo. Has anyone experienced pinging in the intense heat of the desert?

Im running the 93 4x tune with the ACES IV

I haven't had the pleasure being in the Desert heat but could of been some bad gas IMO! I would add a bottle of Chevron techron fuel system cleaner to see if the pinging noise subsidies.
The motor oi changed recently!  Z

Were you using aces to get to 93?  What was the calculated octane at the time?   Pinging is a lean condition, could be bad gas or simply insufficient octane.  Tracking OAR?

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

At those ambients your IAT2 was probably at least 170-200 and theres only so much 91 and ACES can overcome.

I thought of that too. So my next full up I overdosed on ACES.

Yes. I never a problem on previous trips. I'm making the haul again in couple months. Will verify if bad gas.

I had the dreaded pinging again. I am now convinced it related to IAT. Ambient air temp was roughly 115 degrees. AC running full blast. Ping would happen on any half to full throttle accelerations.

So as someone stated, I may be over taxing the ACES IV, 91 octane gas, and 93 octane tune. So I will go back to the 91 octane tune. And yes there will be a performance drop but.......

Wait n see I guess!  IDK if doubling the ACES would help anything, Brian probably knows tho.

hmm... I wouldn't expect the pinging to continue. If its really pinging from knock events, OAR should scale that spark back so it shouldn't happen.

Mine has done it for years. I just know I cant go all out in hot weather, or up an incline.

You never can know exactly what flavor the tuner put on Learned Octane and spark tuning. At very high loads like when at WOT the knock retard won't affect the OAR value with stock values in the tune.


That west coast 91 oct flat out sucks I'll say that...People with good gas need to be thankful. I often pull 2-4 degrees of spark at WOT even over stock values for people that live in the west...It sucks

Damn... I would think tuners would at least incorporate learned octane even at WOT..

Granted I have really good gasoline so I haven't seen high knock values except when my motor was blowing up.. lol

Good information Brad!
