I had trouble with the huntertuned 1000's myself with getting them to idle anything above a 13.5afr. I played with the deadtimes some and have got them dialed fairly well. Post what dead times you're running with them. for 43.5psi FP I have been running (8v-2.33) (10v-1.86) (12v-1.46) (14v-1.12 ...

I never saw these replies, Are you able to DM me? I'll get you a map made for your setup

if you can find a way to private message me, Or send me your email. I can get it to you.

Will you post your fix as well? Incase anyone else runs into this issue? I battled this myself recently and it whooped me. Ended up swapping the map pigtail and wiring, the 4bar to an oem unit, it shows -2 key on engine off but as soon as it fires it goes -19/20 finally.

How is the sensor itself? I’ve had a bit of the same issue not too long ago and replaced the sensor itself and it’s back to normal.

What’s your setup?

Thank you Hondata! I 100% had to come back and let everyone know what fixed mine just incase anyone else has to go through the same thing. It stomped me for almost 2.5 months honestly.

Well she’s finally alive. Ended up changing map sensor pigtail from ecu to sensor, got an oem map sensor new, got everything together, wiped calibration on s300 and started with a basic p74 basemap. Added in my data for injectors and such but the map was only showing -2psi , I got it to start and ...

so while datalogging yesterday with the key on engine off, map sensor reading was scattered all over from must moving the connector itself on the map sensor, I was able to cockeye it halfway on/off and it actually read correctly, then when fully plugged in it read wrong. Going to be digging into ...

tried ecu in another car, and everything worked good. sorry it took so long to get a reply in, life won't stop long enough for me to actually post.


back story, the engine and trans, harness and all was used in a 92 hatch, had it tuned and all then swapped it into the sedan shell, now having these ...

In the launch control settings, I run 5300/5800 +74 fuel, -25 ignition timing. Make sure you have fuel+spark cut checked. You can do always on under 5mph.

Sorry for the late reply, it doesn’t. it still reads positive boost, when I unplug it, it maxes whatever settings I have it on, wether it being stock, 3bar, 4bar. It does pick the sensor up though plugging in and unplugging it. I’m at loss anymore lol

Send me a msg with your setup and I’ll send a file your way. Leave an email

I had changed out the distributor and map sensor pigtail today, the car actually fired up and revved etc, it did have a code 9 though, i left and came back to button up everything and it’s back to the same problem from before , no code 9 now just 16psi + on the map reading, injector pulse seeing 18 ...

I’ve tried another ecu from a running car and it done the thing as the p28 s300 is doing, I’m not able to try this ecu on another car with my 4bar yet.
