Hello everyone,
I have done my rebuild of the d16z6 engine that sits in my civic wagon.
I did the proper break-in period.
But, what I thought is that I had CEL1 code of o2 sensor, and that my tuner will just turn that off.
I got to the dyno yesterday, did the pulls, and the car would just not make power. That is I got 90kw or 120ish HP, where I should have been closer to 150-160hp mark.
Tuner found that I read the cel wrong, and it is CEL 10 meaning IAT sensor.
I did mix up the wires of the IAT sensor and the other connector that sits underneath the throttle body.
I have two questions:
1. Is it possible that I am missing 40 hp because of the dead IAT sensor?
2. Is it possible that I am missing 40 hp because something died in my ECU after I mixed up the connectors? ( I read that happens ).
Today I will switch out the sensor, and see if it is the sensor or wiring that gives me the fault. I have one week to figure out where my power went.
Here are the specs of my engine:
- 12.5 CR
- ARP cylinder head stud kit.
- Elring OEM head gasket (0.7mm)
- Head porting and polish (professional).
- Valve job (professional).
- Port matching to Intake/exhaust manifold.
- Comp cam 59300 camshaft.
- Repolished camshaft.
- BC racing single valve spring set.
- Skunk2 pro titanium adjustable cam gear.
- Edelbrock intake manifold.
- LMA rebuild (for noise).
- New thermostat
- Distributor rebuild.
- Custom half size radiator.
- Mishimoto radiator hoses.
- New Slim radiator fan.
- Walbro 255 LPH fuel pump.
- Retested fuel injectors.
- Teikin PM7 75.5 pistons.
- TP (japan) piston rings.
- 75.5 bigger bore.
- H22 type R Throttle body (62mm)
- King crankshaft bearings.
- Taiho (japan) rod bearings.
- New OEM intake/exhaust valve stem seals.
- GMB water pump..
- NGK BKR6E spark plugs.
- New spark plug wires.
- 3" intake pipe
- high flow pipercross filter.
- 2.25 exhaust all the way back.
- 4-2-1 Ebay exhaust manifold.
- 2 resonators, bigger muffler.
- Exedy clutch.
- Oil catch can (catches oil from pcv and head).
- New cluch release bearing.
- New belt tensioner..
- all new seals, belts, oils and filter.
- P28 chipped ecu.
Bonus question on adjustable cam gear on comp 59300 camshaft - how many degrees do I advance or retard it for maximum gains?
Please help me out, I really spend a whole lot of energy doing this rebuild myself.
