So guys it finally happened. I got to see with my own eyes what happens with the Hondata ECU that I installed this past week. I feel really lucky because I got to see how my car stacked up against my best friend's Si, which is bone stock with 600 miles. Note: Both cars sip 93 Octane.
Mine has an AEM CAI and Hondata reflash with 4000 miles. We rolled out on to our favorite little traffic-free spot, and did a second gear roll...twice. Much to my surprise and dismay, we were DEAD EVEN through 2nd gear. We punched it from probably 35-40 mph in 2nd gear at the 3rd honk.
We punched it at the same exact time. If anything, it seemed like he was moving ahead by millimeters...it was really dead even...but i think that had to do with loss of torque with the AEM CAI. I dunno :confused:
However, as soon as we came to ~7000 RPM, he had to shift, and I kept going. I took it right to 8k on the tach. I haven't figured out where the revlimiter kicks in with the flash, but 8k seems satisfactory enough for me. Right when he shifts, I instantly put 1.5-2 car lengths on him. I continued pulling slightly in 3rd, and pulled more as we both shifted into 4th, when I had to slow down because I was almost doing 100mph:p
We took a U-turn at the end of the road, and proceeded to do another 2nd gear roll, and it was the same exact result, except this time he didn't seem to be pulling by millimeters like the first time. Soon as we had to shift, I put 1.5-2 carlengths on him, and continued pulling more until we shut down just past 4th gear.
Note: My friend has been driving a stick for 5 or so years, and I've only been driving stick for about 4 months, so skill definitely could be a factor.
We had also done a 5th gear roll a couple days ago, because I think the reflash makes this car much better on the highway in 5th gear. We started with the revs at about 3k in 5th gear, and both punched it. We were again dead even, but I seemed to be inching ahead by the time we hit ~80mph or 4k on the tach, which is when he shut down.
Well there you have it folks, finally a real test between two EP3s. Although one can say that this is even more shocking since my friend's EP only has 600 miles, mine has only 4000, so it's not like its much more broken in.....

And now for my impressions of my EP w/ AEM CAI and Hondata: Well first I'd like to say that it definitely feels like it has more torque from 4.5k-6.5k.
Below 4k, by the seat of the pants feel, (I haven't yet driven my friends EP) it seems the stocker has more torque. It is definitely fun to rev it out to 8k on the tach, and the car absolutely screams with the intake at 8k. But I think shifting at 7500-7700 on the tach would do the same damage on a stock EP3.
The biggest difference, and it might just be in my head, but the car seems so much better in 5th gear. When you're cruising in 5th at 70+mph, you never have to downshift to pass anyone, just punch the throttle and go. It makes highway driving so much easier and enjoyable.
So do I think it was worth 600?? Well, it seems that because of the higher redline, the 1/4 mile time will definitely be better than a stock EP3 by roughly .2-.3 seconds, maybe even more, and the trap speed should be up by a couple MPH as well. But what I don't get and what pissed me off was how my friend stayed DEAD even with me until the shift. I would've hoped with the intake and reflash that I'd pull somewhat.....
BUT, I think I'll keep the reflash just for the fun-to-drive aspect, and the fact that I WILL be able to beat stock EP3s. That's it for now, more later when we both my friend and I hit the dragstrip.:D
