shorty Posted May 2, 2014 Share Posted May 2, 2014 So more tune options and saved weight from the loom too. Win, win. Quote Link to post Share on other sites
mindless Posted May 2, 2014 Author Share Posted May 2, 2014 Exactly. I mean the machining part is easier said than done, but short of fitting an AEM system on my car this is way more cost effective. Quote Link to post Share on other sites
mindless Posted May 5, 2014 Author Share Posted May 5, 2014 (edited) 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 fucking 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. >http://youtu.be/4Xvkfr9utro Car feels more responsive throughout the rev range and there is visible increase in low end torque. Power delivery is now very linear – 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.

maddox710 Posted May 5, 2014 Share Posted May 5, 2014 Thats epic mate. Sounds like you have really instant boost response. The linear power will now help you to manage the tyres better. Quote Link to post Share on other sites
mindless Posted May 5, 2014 Author Share Posted May 5, 2014 @maddox710 oh yeah we used to wheel spin and torque steer coming out of every 2nd gear corner. Quite scary especially in this old school track because there is very little runoff. Quote Link to post Share on other sites

ali_legend Posted May 8, 2014 Share Posted May 8, 2014 Sweet looks like your using a p28 with moates ostrich? I have one in my dc2 ATM and it's an awesome but off kit, Crome is fun to play around with too!! Quote Link to post Share on other sites
mindless Posted May 8, 2014 Author Share Posted May 8, 2014 @ali_legend yep you're right – but that's actually the tuner's personal box. When we get everything buttoned up and sorted out we'll burn the tune into a separate p28 box Quote Link to post Share on other sites
mindless Posted June 9, 2014 Author Share Posted June 9, 2014 (edited) 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. >https://www.youtube.com/watch?v=wihSmIsxeRI&list=UUfV0LTGP1px3rhttsjwCPFA 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.

mindless Posted June 11, 2014 Author Share Posted June 11, 2014 (edited) Thanks @maddox710! It's actually in pieces at the moment for easy access to the newly wired ECU. We want to make sure everything is going smoothly with the honda ECU for a few more races and then we'll install the remaining panels up Edited June 11, 2014 by mindless Quote Link to post Share on other sites

mindless Posted June 29, 2014 Author Share Posted June 29, 2014 (edited) Now that we've more or less made the car run reliably after the whole honda ECU transplant, I've had some time to think about improving the aero on the race car. After some research, I've come up with this idea to design a crude "blown" diffuser aero. Basically its your standard solid wooden underbody that bolts into an aluminum rear diffuser but instead of having the exhaust exit where you'd normally have it, I was thinking maybe you can have it exit underneath and through the wooden diffuser blowing directly into the center channel and acting as a blown diffuser. I know its probably a crapshot at best but its better than nothing. At the very least the solid underbody should give us extra downforce even if the blown diffuser turns out to be ineffective Edited June 29, 2014 by mindless Quote Link to post Share on other sites
Glanza Mac Posted June 29, 2014 Share Posted June 29, 2014 I can see your logic and it should work, I doubt you will notice the difference but it should work more effectively Rob. Quote Link to post Share on other sites
mindless Posted June 29, 2014 Author Share Posted June 29, 2014 Yep, really want to try this idea out. Supposedly the exhaust blowing through the diffuser should help suck the air underneath the car and creates more downforce. Quote Link to post Share on other sites
