basic rundown is i have turbo gsr with 1000cc injectors and omni 4 bar map sensor. i have neptune rtp and i cant get it to stay running. sometimes it cranks for a second but is very rough and then dies.

 

talked to james at hrtuning (thanks for quick response!!!) and got a few suggestions im going to try when i get home. any input is appreciated.

 

well it idles. it idles like crap and sounds like its on 3 cylinders, but it idles. dies when i touch the gas. needs some adjusting done for sure.

 

Do you have a wideband oxygen sensor ?

 

yeah, using a plx m250. air fuel is around 14.0. it sits at about 800 eventhough i have it set to idle at 1100. lots of diagnosing to do tomorrow

 

same problem freshly built gsr cant get it to run start and just dies any gas given kills it i have a basemap from xenocron if it runs not longer than 20seconds then dies sounds like **** like something is misfiring but everything is correct trying to get running for a week now what do i do
thanks

 

1. Check firing order.
2. Inspect all sensors for proper function. (iat, ect, map etc.)

 

are you running the appropriate battery offsets?

ignition timing synched?

datalog your sensor voltages and make sure they are all correct.

 

make sure the plugs are in the correct spot i know honda made some of the plugs the same like map and tps, im pretty sure they can be mixed and make the car idle like garbage.
