My EP82 Time Attack/Circuit Race Car
- Thread starter mindless
- Start date
Here's my afternoon session from last Saturday's race!
2013 Circuit Showdown Round 7 - Time Attack P.M. Run (BRC Long) - YouTube
Clocked in a best time of 2m 08.333s just .167 faster/off of 1st place in Bracket E. Ended up at the bottom of Bracket D. Because the .199 breakout rule I opted to cancel my Bracket D lap for my next fastest lap time: 2m 09.324s -- good for fourth in Bracket E earning me some points at least (vs being dead last in a higher bracket)
On the upside I am 4 seconds faster than my last run in this track configuration and 10 seconds faster than when I started racing this year
Next up is my brother's grid/wheel to wheel race. He started 8th, crossed the line 2nd, but ended up 15th due to a 1min breakout penalty (he went faster than the allowed time per lap for the bracket)

It's the first time we're driving the car again after not being able to race with it in the previous leg and a rather problematic 1st leg with the car.
We're now on a new (and quite experimental) ECU setup using a re-chipped Honda ECU tuned using CROME after it became apparent torwards the last legs of the last year's season, and the previous endurance race that our piggy back E-Manage Ultimate just wouldn't cut it anymore.
Because of this new setup and a shortage in 3 map sensors we're running lower boost levels than what we would normally run. (3 out of 3 GM 3-bar map sensors we bought failed on us - heh what are the ****ing odds??)
But even at lower boost, no scramble and getting re-acquainted with the car we're able to reach our previous times easily.
Here in the shakedown/time attack video below, I reach the 2m08s mark, driving it at around 70% still trying to get a feel for the car.
Car feels more responsive throughout the rev range and there is visible increase in low end torque. Power delivery is now very linear â the huge late boost surge that we used to have to manage is gone.
Still, there are a few more small bugs we need to address and sort out, but mainly this has been quite an improvement over our old piggyback fuel management setup. No trophies this race but we have a improved a lot setup-wise and can't wait to get up to running on full boost and push hard next race.
I'll post more photos of the car in action when they start coming out on Facebook.
For now here are some photos showing you what the setup is like and give a bit more detail into how we did it:
The Civic distributor assembly used in the conversion:
Here it is machined and fitted to the head
They had to disassemble most of the race dashboard just for the weekend so they can access things if something goes wrong. Part of the conversion was also simplifying the whole wiring mess. If you notice we got rid of the steering stalk and assinged those to a whole new set of switches on the center console.
Unfortunately no scramble for us until we can sort out a proper working 3 bar map sensor (we're using honda's stock map sensor for now)
Here is the new brain of the car. We were using the emulator last race weekend because adjustments are still being made. Once final we'll burn the tune into a chip and install it in our P28 ECU.

Really happy with the car right now. Last weekend has been our fastest on this track (Batnagas Racing Circuit) ever. We have been struggling with this track ever since we started racing.
We've gotten a proper 3 bar map sensor finally working with the honda ECU and now running back on full boost (1 bar standard, 1.3 bar scramble). As a result I've smashed my personal best time by a whopping 3.5 seconds – from 2m8.333s to 2m4.836s.
Our particular modification route we chose hasn't been the easiest, but it was all worth it. We're still searching for a win this season, but the fact that we are getting faster is something to be happy about. We'll get there.
