Spent another half hour this afternoon.
These coils dont snug on really well. Spent 2 hours making a bracket as the one for aftermarket intake manifold doesn't fit. Just done 1 coat of paint on it. I'll put up some photos later... |

Finished making the bracket and installed it.
The coils do not fit on spark plugs good at all. 5 are still loose and easily removed with very little force. Not keen to start it. I will pull the plugs and see if I can get the coil boots to seat. Photo attempt 1 |

Having my first o2 sensors issues.
Started car yesterday and noticed my fuel trims and afrs were acting strange. Trim 1 flicking from 29-50 but afr 1 staying stable as they should Trim 2 working nicy and fluent up and down a few numbers like normal but afrs stuck 20 unless I rev it and on decel it goes I the 18s 16s 14s for a couple of seconds. It's like I have my o2 sensors in the wrong bank. I tried swapping send reset adaption and the trims go in opposite directions one goes to 50 other goes to 0 and afrs are in the 17s at idle on open loop then 1 bank goes 10.x are and other goes 20afr. I tried resetting adaptions of o2 sensors and re flashed tune and swapped o2 sensors. It's like both o2 sensors are stuffed. 1 reads afr 20 and the other only works at 29 then 50 on fuel trims. It's possible they both got pressure issues last test run but it was only 22psi for 3 runs and soon as it hit 22psi it misfired cylinder 1 each time. Missfire was from goung lean not spark. Bought good coils anyway. Confused... |

Put a new bank 1 sensor in and trims and afrs stayed the same.
Put the bank 1 sensor in bank 2 to and all back to normal. Tried some antilag at 50km like Darwun has as a strash speed. It spools so quick 2 seconds it shoots to 10psi 3 seconds 15 psi and gates open. Launches pretty hard but hard to control boost while on until lag it just shoots to 20psi pretty quick. Did a few logs and runs. Went from map 2 to map 5. A small adjustment in turbo duty cycle was wuick to get on target. Literally 2 runs to get boost on target. Bad thing 1/4 times didnt improve. mph picked up slowly. Slower then I expected. 17 psi 120mph, 20psi 121mph, 22psi 124mph, 25 psi 126mph. All on 6 degrees of timing, 6 degrees 5000rpm, 6.3 5700rpm 6.7 6400rpm. Going from 17psi to 25psi the only gain was 6mph and no et improvement. Quickest was 12.58 126mph 2.31 60 ft. So not going as quick as I was thinking. Increasing timing a few degrees should put some more mph but I just can't put the power down. |

Logs look clean. On a 1/4 run 25psi Iat increase was 11f. start 100f end 111f. 33 degree ambient
Positive thing It is running perfect. Timing perfect, iats low, trans peak 85 degree, engine got up to 115c after a few back to back runs. |

Good luck with the roll racing Brule. I hope your car blows all of your opponents away. Will you have your Mickey Thompson tyres on for the meet?

Yes.

New wheels are on.
New tyres were a debarcle. Ordered mickey thompson et streets ss. Tyre shop was not a tyre shop at all and I had to cancel my credit card. Got some tyres local. re003. fThey feelsoft and will be better then 19s Wheel and tyre are 7.X kg lighter. Mickey Thompson will be going on as my 69ft are still in tbe 2.2 with re003. It feels like a different diff ratio now, much responsive down low now. And tyres are smaller by around 30mm in height. Car had had fluids re-done. Done around 20 1/4 passes so its due. pumped timing from 6 to 10. Feels really strong. 25psi on 6 feels like 17psi on 10. Similar to how the torque was on the rbs ( not as torquey ad rbs). Small issue with throttle body codes but its still doing wot no worries. put under tray back on and cowl which has made oil temps go up average 5 degrees. U will remove cowl for racing. youtube video walk around if current set up. Cant wait for roll racing Friday night!!!! https://youtu.be/adZG-VWwbHw |
