  1. I just found this picture from when my tuner tuned my car. I’m not good at reading these things.
  2. Thanks for the advice everyone. First, I have to invest in a better ECU. That’s the only way the tuner will help me. Then I’ll get it properly tuned.
  3. I assume that can’t be adjusted without accessing the current map with an FC Hako or Datalogit, correct? Are the digits on the right (+0.06) the dead time? I calculated: 1000cc injectors -> 0.989 @ 14V 555cc injectors -> 0.6 0.989-0.6= 0.389 dead time Or at least the nearest value I can get it to. and the injectors (based on last tune): 555/906= 0.612 or 61.2% Is this correct?
  4. I just tried 64.1% and it started and idled fine, except the RPMs seemed to fluctuate a bit more (between ~30rpms) than when it was to 74.2%, where it maintained a pretty consistent idle and stayed within ~10rpms.
  5. I had already installed the ballast delete with the injectors. And I did research on the changes to Injector duty to compensate for the bigger injectors yesterday and gave it a shot. I set it to 52.1% at 0.06 and it stalled out any time I came to a stop, so I set it to 74.1% instead and it fixed that issue. Although, since my last tuner tuned the ECU to work with the 555cc injectors, I based my calculations on the previous injectors and came to ~64%. 48% turns the car and then shuts off immediately.
  6. The tuner I took my car to is famous in Japan, and I assume he doesn’t want to taint his reputation by cutting corners and doing a risky tune. From just installing the injectors and without making changes, the car was able to start and idled better than most eco cars that tremble like crazy. It cruises fine, but runs very rich. I can tell from the popcorn in the rear from just lightly letting off the gas pedal and the smell (no leaks). I was able to drive it for a six hour round trip without any issue, other than what seemed like misfires at fifth gear below 2500rpm. This is my daily at the moment, and I know it’s risky to drive it without a tune, but four of my six cylinders were running very lean and two of them were very rich with the old injectors. I can’t extract my current map and send it to a tuner either because I don’t have a Hako or Datalogit to do so. Unless someone has one they want to sell.
  7. I took my car to a tuner today and he said the injectors are too big for the PowerFC to handle. Told me to get a better ECU.
  8. I don’t have a wideband. I intend on driving it normally until I get it to the tuner in a few days. As of now, it idles fine and cruises fine. I just don’t want to risk breaking anything.
  9. I had the Nismo 555cc injectors. The injector data on my PFC showed 82% at 0.06ms.
  10. Good morning, gents, I recently bought and installed the Bosch EV14 1000cc injectors from NZEFI and it included a paper with injector data for tuning, but the nearest tuner is nearly three hours away, and I just need the car to drive normally until I can make time for the trip. I will attach the picture. I have ap Power FC and was wondering if it was possible to input any data through the FC controller to improve its performance, for the time being.
  11. I looked inside the wells and didn’t see any oil and each cylinder averages about 160psi when I did a compression test.
  12. Hello, I just got done changing out the spark plugs and noticed that cylinders three and four are running extremely rich. My tuner suspects it to be a CAS issue or a coil pack problem, but my split fire coil packs are still pretty new. I’ll add a picture of the spark plugs. Has anyone else had an issue like this?
  13. You’re right! I didn’t know that about the Apexi, until now. It came installed in my car and I never messed with it. I just took it to a tuner. That explains it. I set it to 1.1 bar and it still feels like it lacks in power, but it didn’t cut like before. The -5s are more high-end power, and I couldn’t safely hit 6000rpm. Anyway, these are the results. Thanks for the help, brother.
  14. It turned out to be the first one. Took it to a specialist in my area and it was a short in the wire from the sensor to the ECU. A body shop I took my car to probably nicked the cable. A new cable fixed the false reading of 1.87kg/cm2. I wonder if the problem of not being able to boost past 6000rpm is still there.
