I just got back from for a run with the stage 1 tune, see attached. I will try get out in the morning and do a run as you have suggested and post the log on the stock ECU.
From what i see on datazap mobile(which isnt much) still looks like its running lower than stock ignition timing. Which if you dont know ign timing and boost = cylinder pressure.. the more ign timing your run the faster you are… stock runs at about 15 degrees and your lower than that which is most likely whats making you so slow!
If i were you i would ask for “19 psi flat boost with 17 degrees of ignition timing and 6 degrees of shift timing”. .. and tell him your running e40 to e50 fuel… if you decide to ask for that
Cheers I will try and ask for that and see what he comes back with.
Ryan is asking me to do more runs on that stage 2 1.03 Tune? Now I am confused, and definitely a little worried about loading that tune back on and doing more runs.
Just flat out tell him you dont feel comfortable/safe running 1.03 again… tell him boost hit 1.7 bar at one point and ign timing is crashing..and when you say backfires are you talking about misfiring or like pops and burbles when letting off the throttle?
I will say the jb4 and cpi was a really smart purchase… absolute best logging device and there easy to read!! Ek1 logs are terrible imo
It sounds like the pops and burbles when letting off the throttle though I am not off the throttle I am still WOT. I start a run WOT, the engine gets to around 5K rpm loses power and makes the pops and bangs sound until it changes gear, when it changes gear power comes back normal and the pops sound disappears until the engine gets back up to around the 5k rpm again then loses power and has the pops again.
What are your plugs gapped at could be spark blowout due to the higher boost on the stage 2
I did not gap them, maybe this is the problem. I left them as I thought by Nathan’s post they just leave them at the factory setting. See pic attached where Nathan says he leaves them at the factory m45il gap. I can pull them tonight and gap them. What gap do you recommend?
If your using hks yes its recommended to start at stock hks gap but if your experienceing spark blowout your have to gap down… i cant say that your experiencing blow out forsure without driving the car myself. I had blow out with stock gap on hks and i know a few other people who have aswell… you could wait for a revision and if it still does it on the revision you could try it or you could pull them and knock the gap down to .026- or even .024 factory is .028
Does it feel like a bunch of fast stutters at high rpm?
No it feels just like the pops and burbles I have when I back off. When it pops at WOT I can feel it through the car and the power loss with each pop. My first run I thought may have backed off the power as it was the same sound as the pops and burbles. The next couple of runs confirmed I was WOT and above 5k RPM.
If its not spark blowout no need to regap them… bef dosent need to be gapped as it adjusts spark dwell
Thanks for the info, did you post the comparison? If you can add it that would be great
Ticket will reopen if you reply.
Cheers, Another log on revision 1.04 attached, the car felt much better, boost felt good and could not feel any issues though I am still seeing the low timing. I have asked Ryan for an explanation as to what this means from a EK1 Sxth context. I will turn on the 6 knock learning values later and do another log.
Thank you for posting that, after looking at that log you supplied I cant wait till I get my JB4 next week, so much information on one log it's great.
yea it looks much better. seems to be making progress
