{USERNAME} wrote: yes the pinging issue is due to the tune not being right and the ecu not being set up corectly.. it was fine untill the day after the tune, then it started pinging.. the original tuner gave me stupid excuses as why it started pinging ..lol i was told i messed up the tune because i connected the o2 sensor and ait sensor:roll: ..(although the o2 only adjusts fuel within 15% of idle and the ait was not activated when it was set up so what i did had no effect.). in my opinion the tuner didnt add any air temp ignition compinsation in the ecu set up. as soon as the intake temp rises over 30 deg c it starts pinging.. so its pinging because of too much ignition timing between 2800 and 3500rpm @ and over 30deg intake temp. i have played with the tune a bit and removed some timing but i dont want to change it too much as im still not to confident with modifying the tune.. so since the original tune was done ive added the 3" exhaust, added more boost, now i just got to find a decent tuner to tune it again..  there is a dyno day comong up in 2 weeks so im hoping to have it tuned by then?? if not il just remove more timing my self to be safe.... smart idea Troy. If its still pinging too much for your liking by the dyno day, I'd err on the side of caution and not put it on the dyno day for safety sake. Its a pity your tuner isnt decent enough to know what should have been done in the first place. It will be interesting to see what kind of figures you'll be pulling once you get the car tuned RIGHT! Sounds like there could be another 10-15rwkw just with the added boost alone. On a side note, Ive PM'd Tim for one of these pulleys myself. Just waiting on his reply for me to transfer cash.

Makes me wonder what we will need to do when summer sets in. Considering neither of us have intercoolers, would we need to back off more timing again during the summer months?

i guess it depends on how good your tune is??

This good tune that you speak of will need to have timing retarded in summer im afraid, you realy need water to air cooler mate then add back the lost timing.
To give you an idea im running 6.2psi with base timing at 30* on shell 98 and i get slight ping, before i was running 10psi with 25* base timing and it pulled pretty well now at 6.2psi it pulls just as hard because of the higher timing. Get this tho with my raptor setup i was runing 8.5psi on 30* base timing and i didnt get ping. Got any 0 - 100 vids mate, i used to get mid 5s in the raptor charged xr8 auto with 3.91 lsd (300,000 k motor and trans lol). Brad |

so far ive ran about a 6 sec 0-100 in mine..with 3.27 diff..
i havent tried with the new exhaust and more boost yet.. now traction is becoming an issue.

Your car sounds like so much fun, i dare say your hard work has paid off. Can you not help but smile when you put your foot down.

loss of traction SHOULD me an issue lol, as i type this i picture troyman smilling as he types away about his ed lol.
Troyman i wouldnt go lower than 3.45 as you will run out of revs real quick, infact i probably wouldnt change ratios if ur already losing traction as it will get worse. Im actualy going to change to 3.08 an getting a lokka. |

See i got my 3.08 because i was planing ahead.....not really it was in a wrecked fairmont and i only had GLi 3.23(whatever it is)

RE - Traction issues... Has anyone proven that putting something heavy above your diff slows you down MORE than the extra speed the extra traction from 0-40km/h would provide?
Have you tried 255's or more on the rear? Have you tried running mid twenty PSI in the rear tyres? Obviously I am not a drag racer of any note, but hey - If you're doing mid 6's or below then these suggestions would take about ten minutes (other than finding some decent 255's to put on) and if you don't spin the rim on the rubber you'd probably loose a bit of time off that six second mark huh? Six seconds is already pretty quick for that kind of setup isn't it? |

I dare say mid 5sec 0-100kph is what you'll be getting Troy.
Hmm with the smaller pulley, and retarded timing, would you feel much over the standard pulley do u reckon during the summer?
