JSP C900 Staged ECU chips

JSP C900 ECU remapping (LH2.2 and LH2.4)

You can run larger injectors, larger turbo and have good air fuel ratios across the board. This is critical for engine longevity & true performance – no more guessing.

In order to create a correct chip for your car, some data gathering is necessary. The first are some details on your existing engine setup (turbo, intercooler, injectors, etc.). Second, to understand how the car is currently running, the air/fuel ratio and Air Mass Meter (AMM) voltage is needed throughout the RPM range. The best way to gather this is on a dyno with a good data logger, but it can be done on the highway if you have something like the LM-1 unit. A wideband O2 sensor must be used to get the correct air/fuel ratio and the AMM voltage can be gathered by hooking a voltmeter on the orange wire of the AMM.

Once this data is received and analyzed, a new chip will be sent to you. Custom remapping can be done as well. If you are close to western North Carolina, bring your car in and a dump of your rom will be put into a laptop and an emulator will drive your car, logging the necessary data & making changes in real time. When everything is right, a chip is burned.

All remaps are kept on file to make future changes very easy, even over long distance.

NOTE: Since this chip changes fuel maps, a Rising Rate Fuel Regulator should not be used with this chip. A 3.0 Bar fuel regulator is recommended.

Price: $POA for inital chip with 3 free reburns for fine tuning.
$POA for onsite custom mapping.
$POA for major remapping after an engine upgrade.
