Hondata 4bar map sensor
Hondata 4bar map sensor
Hello,
What is the map sensor supposed to read when the car is off? My car is turbo'd and I believe that the map sensor is faulty. Right now it is -.9 MAP when trying to crank but car will not start. Is this correct?

Re: Hondata 4bar map sensor
And what does it read when cranking?
Re: Hondata 4bar map sensor
I will try and post the datalog of the issue tonight.
Re: Hondata 4bar map sensor
Also, before I actually try and crank the car with the key on ignII the wideband in flashpro manager is reading 29.40...
Re: Hondata 4bar map sensor
Don't worry about that, as it is not running yet.
Re: Hondata 4bar map sensor
I attached the starting MAP from hondata as well as the 2 datalogs i took while trying to start the car. I tried reducing the cranking fuel trims because before I did this the car would crank then backfire very loud. Now it just cranks and cranks but wont start. I checked timing, I checked spark, and I am getting fuel. I am not sure what else it could be that is causing a no start. Car idled fine before I added coolant.

Re: Hondata 4bar map sensor
Will it start if you put the stock MAP sensor back in and change the settings back to stock MAP sensor?
Re: Hondata 4bar map sensor
i tried the stock map but no luck.
Re: Hondata 4bar map sensor
If it does not start with the stock sensor then it is most likely not a problem with 4bar map sensor. How are you checking for fuel and spark?
Re: Hondata 4bar map sensor
I put a node light to each injector and the gauge is reading 60 psi at the rail. I pulled each spark plug and grounded them then cranked the motor each one fires. I not sure what else to do
Re: Hondata 4bar map sensor
Is there evidence of the injectors actually spraying fuel when you pull the plugs?
Re: Hondata 4bar map sensor
Oh yeah, I pulled the plugs today and they were wet with fuel so I dried them and then reduced the cranking fuel trim by 10% but still no start
Re: Hondata 4bar map sensor
If you put the stock injectors back in and return the ECU to stock will it start the vehicle?
Re: Hondata 4bar map sensor
Haven’t tried that yet. I will try it tomorrow.
