Any help pleaseee!!!!

 

gday there

sorry to say this, but i'll make it short and sweet

GET A REAL EMS and GET A GOOD TUNE

that will save you money, and save that motor of yours (plus alot of headaches and forum surfing)

 

Stop beating on that car or you're going to blow it up. 13.1 AFR in boost is way too lean. Should be 11.5-11.8 to be safe. Get a tune before you grenade that motor.

 

You need to get it tuned... d15 stock blocks are only good for like 180whp sooo... Im sure you are leaning out 310 injectors are only good to like 220hp

 

I have a old style hondata ecu that i wanna run but no one in town can tune it , so iam not sure what to do! .. And is there truthfulyy anyway to reach it out more? Posibly running pr4 ecu? Or should i invest in fuel rail and regulator tell i can afford a tuner .. Thanks for yalls help and being truth full .. I have a b18c 98+ spec just sitting here waiting for this motor to give .. But iam trying to sqweez couple more months outa this motor

 

Well Hondata does have a trade in program.. A pr4 will do nothing for you, diffrent maping of fuel and timming. I would just get a new hondata and tune, no need to break down far from home.
