TunerDyanamics Posted May 14, 2018 Report Share Posted May 14, 2018 Hello everyone, Below are the specs of the engine 2JZ GTE VVTI Stock Long block with some upgrades CAMS : 264 Turbo: AR70 Journal bearing Boost Pressure: 1.5 Bar Spark Plugs : NGK BKR7E Fuel : RON 97 Piston: Thailand Made Stock 2JZ Pistons ECU : LINK Storm G4+ RPM Limit to : 7.5K RPM Timing Table : 2500 8000 28 28 28 28 28 28 28 28 28 26 30 26 25 25 25 25 25 25 25 25 25 25 25 19 14 14 14 14 14 14 14 14 14 24 18 15 13 13 12.5 12.5 12.5 12.5 12.5 12.5 22 14 13 12 12 12.5 12.5 12.5 12.5 12.5 12.5 20 12 12 12 12 11 11 11 11 11 11 TPS Vs RPM After A little three months of engine running We open engine a apart for some upgrades we notice that there is pitting on the pistons on the exhaust side. Wondering is it piston is not genuine or there is a problem with my timing table, do think that the numbers in the table are very very minimum? Did check for Knocked with Links knock equipment, no sign's of knock. Wondering which part went wrong that cause the issue. For fueling AFR is around 10.5 at WOT, engine make 354 WHP Already did check for timing drift there are no signs of it drift from 1.5K RPM to 4K. This have been hunting me for the past week, hope that you guys can shine a light on me. Quote Link to comment Share on other sites More sharing options...
iecku.tavea racing Posted May 14, 2018 Report Share Posted May 14, 2018 Why do you use tps instead of map as axis on a turbocharged car? Quote Link to comment Share on other sites More sharing options...
Brad Burnett Posted May 14, 2018 Report Share Posted May 14, 2018 Could you maybe post a copy of the calibration that the car is running, and maybe a log? Quote Link to comment Share on other sites More sharing options...
