Re: Rebuilding Ty #284
I've been driving this around...alot. First day out I drove it around the block a few times, and checked for leaks and such, only issues I had was power steering fluid was low, and the belt I got was a half inch to long, both of which I fixed, and then I proceeded to go on a 200 mile road trip around flint. I stopped from time to time to check things out, and everything looked great the whole way. While I was doing this I tuned the truck, I started off with the idea that I was going to be flowing more air, and was going to need more fuel to compensate for it, i so i upped the F30 for F29 table? (table that you usually start tuning with and find your idle afr, but its base fueling for the engine) an additional 5 units and started. basically the whole way I was pulling fuel though, but, using the tune I had for the stock heads and such was still pretty nifty, and it didn't take much change overall.
also somehow during this run I burned out a fog light. I looked on here and there were a few threads saying that harbor freight has fog lights of the same type, and sure enough they did. with a bit of soldering they fit right into the stock housings and even are the right color and intensity.
the next day I upped the boost a bit from an open waste gate to about 10 psi worth of DC. I did this not to try an go fast, but I find it helps me with tuning when im actually having the turbo start to do what its going to do in the final tune. I drove it like this for an additional 100 miles. After which I decided to do a few WOT runs and see how it did. I had no issue, it built boost fine, held it, and I had no KR, although i was running a bit rich at 10.8:1. I logged it and made some adjustments but it seemed to be taking it well.
I then tried my first boost launch, I noticed that my stall seemed to happen right around 3200, which sounds high, but felt great. It barked all 4 tires and launched hard, it felt like the whole truck jumped straight into the air. During that time I noted that I had achieved 2* of KR due to a poopy low fuel issue right off launch, I fixed it, tried it again and it went away. I then upped the boost to 15 psi and did a couple highway pulls. it was running rich at 10.6, but still felt alright. I headed to the local cruise in...
it was pretty empty, and I had the strip to myself (empty industrial road) I had 20 spectators that were shouting something along the lines of "that's a..that's a typhoon!" I sat at the line with an evo, but he just kinda rolled past me, which was exactly the thing i wanted to race. but, I decided to do a run and log it, and do some tuning at least. I managed 2 runs with 0 kr, and it felt like it was pulling hard. both times I tuned afterwords and both times I was pulling fuel. I decided to do a last run and this bike pulled up next to me. I decided it was worth a try and ran him, he got the jump on me, and I didn't get a real launch...he ended up winning by 2 lengths. Still felt good. after I left is when I got in a race on the freeway with a TBSS, and I was really surprised to walk an ls-1 powered anything on the freeway...at 110 I was still walking him...
I decided I need to check out my knock sensor, even though I know it worked before this last build, and I did actually see some knock during this extravaganza, it doesn't seem right, I see on C59 there's a knock sensor test that I think Ill try out. hopefully this week my batt relocation kit gets here and I can install that and my alky control kit.
I hope I can get that all in before this coming weekend and maybe get some tuning time in, I'd like to go to the track and get some real numbers.
