BRP/SOT Hotside SC Install

where is the new dyno plots 
Car is still running perfect - hit 1500 miles on it today. Plugs look great (little rich below VTEC) and idle, start, boost transition is seamless.
Also hoping to get a new ELF chip this week to smooth out the AF curve. Currently have to run it around 10.5:1 below VTEC in order to prevent it from going lean at vtec engagement.
2k-6k 10.5:1
6k-7k 12.4:1
7k-9k 11.8:1
Still pulls amazingly strong below VTEC (can break the tires loose in 1st and 2nd gear will nothing more than mashing the pedal to the floor) - but I am sure there is more power/torque available once the AF gets sorted out.
I have been talking to a friend that works for a shop that has a couple of the BETA AEM piggy back fuel and timing controllers. They have been testing them on FI civics and integras. Word is they are pretty solid and he is going to see if the shop owner will let me borrow one for a week or so. Only one of the units they have is chipped to do fuel/timing/vtec control - the other is just fuel and timing (probably the loaner I would get if he will let me borrow it).
AEM says they are still 2 months out from releasing it for sale.

I was reading some posts on the SOT forum and I was wondering what obd2 tool are you using that allows you to monitor/log knock?
I wrote my own software that monitors the timing output of the OBDII and throws up a knock indicator if there are certain changes in the timing under acceleration. I could not get it to work perfect so this week I am monitoring the actual knock sensor using an analog input card on the laptop to detect knock.
By weeks end I should be able to monitor and log the following:
knock
rpm
injector duty cycle,
boost
AF
IAT
All in real time at about 600 or more samples per second - 100 samples of each data point per second (or about 3600 data points in total for a 3rd gear pull). Still have to work on the filtering for the knock sensor and calculating the RPM and DC from the injector pulses - boost, AF and IAT are already done.
The above listed OBD tool is pretty decent for $83 (with free software). Can report all DTC and tell you what they are, monitors most all vitals in real time and allows you to log them to the laptop.
Ah nice
I have OBDII Pocketlogger, and I can see all DTCs and reset them, but my sample rate is about 5-6 samples/sec, so its really sucks if I'm trying to do even a simple log like TPS, RPM, and Timing
I was wondering how you were seeing knock, since it doesn't look to be something the ECU reports, but it seems you're doing something similar to what I was doing on my 96 VR4, watching for irregularities in timing. If you're getting timing pull you're getting knock, lol

I want to add TPS and vehicle speed to my software. Ultimately what I want to create is a street dyno software package. I already have a simplified version that uses GPS, but it is not completely accurate(again because of sample rate). With the analog card I can use TPS to trigger the data collection and "guesstimate" HP over the RPM range using the vehicle speed (speedo) input.
Looks like the pocketlogger is not effective for actually logging. The OBD tool I am using allows much faster datalogging than 5-6 samples per second.

I have a feeling that he didn't get the numbers BRP was hoping for, that's why there is no dyno.
Want to do IC and non-IC on the same day - shooting for first week of April since I am traveling the next two weeks.
I will post up some pics of the IC kit once I get it installed.
