Re: First dyno disappointment...

http://share.cx.com/48tgN6 This link is what i mixed together and tried today. It didn't seem to have much power at all. So, i loaded one of the other tunes. http://share.cx.com/msbgmd This link is one i loaded up adjusted the kconst and latency and it idles great, but it's SUPER rich trying to driv...

Re: First dyno disappointment...

http://share.cx.com/ZrFrWj :text-link: Try and see if you can download and see this bin. I tried something and i hope it works. If it does work, this is the current tune i was running. I had to modify the kconst and latency so the car would idle and drive. Again, this is AFTER going to a tuner. The ...

Re: First dyno disappointment...

I have read a little about listening for knock with a recording device and also people using knock lite. I like the idea of a knock lite but do they work well enough? I don't think i have the skills for listening for knock so a knock lite seems to be the simple route.

Re: First dyno disappointment...

I'm glad you agree with that man. I have been scratching my head trying to figure this out. Obviously the tuners I used didn't do a good job at all. I been thinking of loading one of the maps with 740 injectors and making it work with 550s and leaving it at the 15 psi setting until I can find a good...

Re: First dyno disappointment...

But, if the primary map is almost identical to the knock map, wouldn't that mean the car is running as if it has knock but i actually doesn't? I'm trying to figure this out before i waste more money bring it to a different tuner. If its something simple i can fix, id rather give that a shot and deal...

Re: First dyno disappointment...

OK! After i posted the last comment, it started eating at me. So, I cranked up the laptop and looked at the timing and knock map. BINGO! The stock map and the knock map at the exact same, with some small differences. http://i304.photobucket.com/albums/nn171/robertduhon/timingmap.jpg http://i304.phot...

Re: First dyno disappointment...

If I was on the knock map, would it show up on the nistune as knock? It's possible I am, just don't have the knowledge and my focus just isn't there.

Re: First dyno disappointment...

Well, here is an update. I switched from draw through to blowthrough. I sealed the z32 maf up and have the bov before the maf and after the intercooler venting to atmosphere. I did tons of boost leak test and and few other ins and outs. I ended up messing with the kconst and the latency and was able...

Nistune problem

OK. My car is driving different from what the tuner put on it. It's idling terribly lean and rough (17.5 to 18 to be exact). Vacuum shows at 11 in HG, also. I did a boost leak test, everything check out fine. Checked: fuel pressure, maf, and wire connections. All came out fine. I also noticed the rp...

I don't see it mentioned anywhere but did you upgrade the fuel pump? If not that's most likely why it's leaning out at the higher RPMs. I also have to say those low RPM afr numbers are horrible and there is no reason I know of that it should run richer at low RPM to allow running richer at high RPM...

If they had such a issue with the fuel being lean why is it 10.6 afr down low which kills the spool?? That is what i was trying to figure out. Everything I'm saying is what they told me. I might not know much about tuning but i can compare other tunes to mine and i noticed differences which brought...

From 4700 to 5700 there's a big issue. do you have a wideband? If that graph is correct its rich before 6500rpm which causes power loss and lag. They had issues getting things to work out right on it. I think the major cause was i had the stock 240 sx filter in and not the 300zx filter. They couldn...

Leave the kelford cams I don't know why there saying go with stock cams not bashing anyone but the stock cams suck. You have a decent power band if it was for lower boost meaning the power doesn't fall off. About the diff no it doesn't affect power it only affects rpm x mph. I know the graph doesn'...

Looks like your hitting full boost at 4500 which is not right for the turbo you are using. you should be hitting full boost at 3500. Timing seems to be the issue try going to another tuner I know it sucks dishing out another $400+ but you should easily be making 400whp I still think you should go w...

Boost leaks or a crappy job tuning timing maybe? I boost leak tested at 25 psi. I didn't find any with soap and water. It leaked down around 1 psi per second, which i was told was good. I might do another leak test tomorrow to see if one popped up. The tuning was done by corr performance in kenner,...

I apologize. I'm a noob but i'm learning. This is what i found on the duty cycle. If i'm reading this right, there is a bunch of room left. IIRC, I remember them saying it was leaning out on the top end and they couldn't getting it to enrich. I could be wrong on that though. I really need to get the...

hope this works. Need some opinions here. What do you think of this manifold? What do you think needs to be changed? Boost creep issues at 5k are a major problem and i need them fixed to hit 7500 rpms. Does it really need a 44mm waste gate or not? http://i304.photobucket.com/albums/nn171/robertduhon...

That wouldn't be to bad of an idea if it was done right. As long as it wouldn't cause to much of a flow interruption, i don't see why not. The only question then would be how much is to much or enough?? You'd almost have to weld on a small piece, bold it all back up and go for a run to see if it cre...

I have about 3/4" at 2.5" then to 3" all the way back to the fart can. No cat or anything. The waste gate dumps out of a 1.5" pipe to the atmosphere.
