I did a Mini Me swap with a full port and polished head. I pulled my plugs after 500 k of driving and there all really white. . . . not even close to golden brown. this could explain the lack of power.

We have emissions testing in my area. there gonna plug into my ecu.

any suggestions to richen it up?

Have it tuned.

slowDB7

What year is your car.?

doublezerohatch

have it tuned? have what tuned . . . the motor was just tuned up when I did the swap. plugs, wires, dizzy cap and rotor, timing, timing belt, water pump, seafoamed the engine . . . .

Anyone else with a better response please.

What injectors are you running?

Ok you are ******* retarded. If you dont know what tuning is please give someone else your car and drive a stock Geo or Kia.

Hey i like my Rio!

how the hell have you put together a motor like this and not know what tuning is?

tuning means take your car and get the ecu tuned, the stock ecu map cant compensate for all the extra air going into the engine, making it run lean.....not a tune up genius

if your cars obd2 you'll need to get an obd1 jumper harness and obd1 ecu cuz you cant tune an obd2 ecu

OP. Tuning. Not a Tune up. Look up EMS' like Neptune RTP, Hondata S300 and CROME (which I don't recommend because it's out dated and not being developed any more).

I've never read in any mini me write up where it was ever mentioned that it was necessary to get the car tuned. Maybe at the most an adjustable cam gear depending on what hardware you had installed. It would be best if you could run a chipped OBD1 ECU with a nice basemap on it to get the most out of your configuration.

My money is that the injectors you're running are too small.

My car is a 2000 civic had a y7 I put a y8 head on it.

I am using the stock y8 injectors that came with the y8 manifold

I know what a tune is, and a tune up.

I want to stay Emmissions legal and keep my OBD2B system. I know I could just get a jumper harness and obd1 P28

Im running a y8 ECU P2P

I was confused because in my first post I said I have emissions testing here and they plug into my ECU . . .gotta stay OBD2B . . . didn't think someone would tell me to tune my P2P . . . . no tuning here unless you can somehow tune an OBD2B

Whats the next size up Honda injectors to try .. . from what?

slowDB7

only way to tune obd2 and stay emissions legal would be a piggyback fuel and ignition controller, but ive heard bad things about them so not many people suggest it

You may be retarded or have visual problems.... or you just don't know Honda's... I said in my area has emissions testing and there going to plug into my ECU . . . .which obviously means I have a OBD2B car. . . . which you should know needs to stay OBD2b. a Mini Me swap isn't worth paying 500 a year for a conditional pass just to burn up a little more fuel.

Can you post a pic of your plugs?

Well, those are the right sized injectors. Going up in size will just be a whole 180. Then you'll be running too rich. Adjustable cam gear maybe? A pic of he plugs would help.

No you are. I have a 98 Civic with LS Vtec and tuned P28 with Hondata and I have emissions testing here as well and I pass each time with my OBD1 conversion. The CEL turns on and off but they cant communicate with the ECU, PASS because they think it is there equipment not working. If you wont pass with the OBD1 conversion then you have a OBD2 ECU to put in for emissions then swap back to the tuned ECU after. If you are running Y8 injectors there is no reason for it to be running lean, more likely you dont know how to read plugs, dont feel bad it is hard to do correctly. Hook your car up a wide band and see the the AF ratio is under all driving conditions. Stock Vtec ECU and OEM injectors should not run lean. Unless your injectors are super dirty or you are having a fuel supply issue. Now if you are running D15 or D16 Vtec-e injectors then yes you will be lean because they are smaller. Oh and if you plan to try to run larger injectors you need to have a tune so the SCU can properly control the injectors.
