I think you meant the change in velocity over time is acceleration--not force. So using these physics terms I would say that the JRSC has more jerk or change in force such that the forces build over the rev range, and as such is the case, start off with relatively mild forces. Other kits or cars with flat torque curves yet with the same peak torque as the JRSC will not feel jerk over the rpms; they will feel a large constant impulse over the rev range that the JRSC will only feel at the end of its rev range. Right? |

Has anyone here driven different FI setups on track or autocross? Can you comment on what's easier to handle?

Anyone get the p0171 bank too lean code? System has been running great for the last 1000 miles when I received this code coming home tonight. Google comes back with all sorts of troubleshooting. I disconnected the maf, cleaned it and reinstalled as a first step.

Following up, I cleared the cel today and went for a short drive. Looks like it shows up again in the Ecutek dtc tool. I sent an email to tech@jrsupport with the log from that drive. Will be checking engine bay out after work, see if I can find something amiss.

Lean code problem could be due to oxygen sensors or fuel injectors or fuel pump or your MAF although you had cleaned it. To me, it doesn't look like JRSC has a problem as the CEL is related to fuel supply not air. I would clean MAF and air filter again. Then, I would check the oxygen sensors. Maybe running an injector cleaner could help. |

Stock FRS with the C-30 JR Carb tune. No other motor mods.

I have the same configuration and I was checking the possible causes. If you search the forum with keywords p0171, brz or frs, you will find the other possible causes. One P0171 CEL was fixed just by cleaning the MAF sensor. The other one was a vacuum leak under the intake manifold (a common problem with FI and there is a sticky in this forum). Search and go through the checks and clean ups, I am sure you will fix the problem. Good luck!

Matter of fact I just cleaned the maf again and did the hoses under the manifold. Clamped those and went for another spin. Same code reappeared. Noticed at idle it stumbled. Rpms drop then surged up to keep motor alive. I cant hear any leaks from the engine bay. Short term fuel trims were -24 to +32 during the drive. Huge swing
To clarify, I clamped the 2 hoses that go to the evap sensor and 1 hose that goes from sensor to the intake manifold. Last edited by amcp1; 08-07-2017 at 08:44 PM. Reason: clarity. |

Has anyone replaced the air filter? It appears to be a custom part made for Jackson, but I would imagine any filter with the same approximate dimensions, sufficient surface area, and correct size outlet would work. I hate cleaning these K&N filters, so I usually keep at least two so I can just change it and then clean the other at my leisure. Has anyone found a fitting/compatible filter? I haven't taken mine off to measure it, hoping someone already has the info.

There is a non-JR branded version of the filter availabe, and you'll also want to buy a K&N cleaning kit. |
