Re: A Guide to Cheap DIY Datalogging

Re: r34/c34 factory boost sensor best results?

hey matt. thanks for the reply now i'm just thinking out the box and dont have any real knowledge on these types of sensors, however considering anyone that runs over 18psi will have trouble with the factory boost sensor that is limited to 18psi at 5100mv, wouldn't a 30psi 5v sensor work just the sa...

Re: Nistune Release 1.2.80

hey matt,
so just wondering why one of the injection modifiers were removed with the new update on the r34 ecu.
the one i'm referring to is the option to adjust injection duty without changing afm settings unlike using k constant?

Re: boosting injector trigger wire amps/volts?

hey matt, thanks for the quick reply yes the stagea is running on dedicated LPG and the rating for the injectors isnt in cc's as lpg injectors mostly go off l/min flow capacity so i guess its quite irrelevant however they are the biggest lpg injectors you can get for a car. The feed for the injector...
