Random question about the JB4 in the IS200T FSport. I have everything hooked up as it should be and the car feels no different. I have the HPS charge pipe, BMS intake, awaiting the PPE catless DP from FIGS (apparently a 3-5 week wait ugh). I am also awaiting the USB cable to log/connect. I was also told that the boost gauge in the f-sport doesn't show the "tricked" boost numbers per BMS. It is almost like the device is shut off. Almost feels like the car runs better on the stock ECM. I run nothing but 93 and sometimes 93 mixed with VP MS109 (unleaded). I guess it isn't like the VAG 2.0TFSI/TSI/FSI engines where you slap on a DP, get a uni/revo/apr stage 2 flash, and it mooooves.

Yeah. It’s only funny if it don’t happen to you. With our cars we are past 2K so quick it’s not really a big deal. Also if you launch the car off stall you are over 2K anyway. Stomping it from idle yes you feel the lag, but even stock the car is impressive when launching off the stall (dare I say just as quick as my old 350).

I also came from the VAG scene. I had a 2002 VW GTI 337 with every bolt on available and it was definitely noticeable. I got the 200t with the same thoughts, but Toyota ECU re-flashing is still fairly new and we're just waiting for a proper tuning program. The piggyback system does a decent job, but a re-flash tune like the APR, GIAC, UNITRONIC etc would yield more gains.

Drive it around for a bit and you should feel a difference.

As of now i believe there's only 2 maps available (Map 1 +4psi and Map 2 +5 psi). With the OBD port connector and the JB4 application (mobile or PC) you are able to see engine readings such as AFR, boost, oil temp etc for data logging. I know all the readings are not working since BMS still needs to make updates, but eventually you will be able to adjust boost by RPM, monitor engine vitals for E85 mix etc.

we’ve seen a dyno for 262whp and rumors to be more than that. We also have a torque issue however a company called dimsport is quoting 300-350tq. Our handicap seems to be access to the tune itself which is

Is sketchy a good thing? It peaks and builds back up mid curve It looks great to me. However it can definitely use improvement and an increase in power. Most of our dyno torque curve readings can be jumpy that’s because of our high compression. 1psi jumping up or down anywhere on our torque curve could be the difference of 10-15wtq which you’ll see on the dyno reading. I just wanted to point out the red line is completely stock which is what Lexus did in attempt to make the power curve feel naturally aspirated. The purple line is stock with JRC stage one tune. The green line uses only a downpipe and JRC stage two tune stock intake/exhaust.

Right! This is the kind of result i was expecting for our motor but after 3 years of ownership i am barely seeing 250whp with bolt ons. I know this is still a FWD Honda, but wow talk about potential. 
Sorry for being a negative Nancy.
