ok now let's get down to business.
Cybernation turbo kit, 550 cc 3 ohm injectors (yeah I know), ported turbo/manifold, ceramic coated mani/exhaust. No Cat 3" turbo back. open wastegate dump. Intercooled, custom intake. Running minimum 93 octane. This is a friend's car, that I installed turbo/piggy back last year. It never ran right with the fueling being adapted out. I have to say the software and hardware with this kit was very very poor. Fuel/oil lines, intake piping. I had to fabricate/modify most of it myself to get it safe, or even close to fitting.
I removed all the piggy back garbage, and installed the hondata. Had some communications problems due to non resistor spark plugs, but finally got that worked out.
Only problem right now is the Air intake temp sensor is throwing a code, showing the cel, and reading ~95 deg F constantly. Even if I unplug the sensor it reads 95F. I checked the wiring to the sensor, I have continuity where I should, and I don't have any shorts to ground. Sensor resistance was ~3300 ohms when I tested it. I tested the power across the connector with the car on and I am getting 5V. factory service procedure was followed, and Im at the point where it says replace sensor, or replace ECU. Because the reading says 95 regardless if the sensor is there or not, Im a bit worried it may be the ECU. Any history of this?? Can i safely test a jumper across the connector to see if 95F changes? BTW the car runs fine, it's just that i dont have any AIT correction. (does timing get affected, or just fuel?)
Ok, now I have just a general knock question. I have tuned the fuel map for low speed cam from vac to 6 psi, and up to 5000 rpm. AFR monitord with LM1 wideband and the stock wideband log. The whole time I was watching the knock Voltage like a hawk. Never saw anything above like 0.2 Volts. I noticed the knock threshold is ~5V.
For those with experience, how sensitive is the knock sensor. What voltage should be considered the danger zone. When is there audible knock?
And for the creators of the Cybernation base file (thats what I started with) how is the timing on that file? Is it mild timing? Is it tuned for 91 octane (I have 93) . Are there any other things I should know about the base file? How agressive is the Vtech transition for that file? Does it need more fine tuning for the turbo? To be honest My plan was to tune the fuel and timing and leave the cam position stuff alone. Without a dyno I don't think it's worthwile, and the owner doesn't want to spring for a few hours on the dyno.
Car feels much faster to 5000 Rpm and spools ~1000 rpm earlier BTW
Thanks in advance.
