big-phil Posted March 22, 2013 Share Posted March 22, 2013 (edited) Needs lots of up top tuning, but i feel good about the possibilities. My tach still Doesn't work I've purchased three tach adapters, Dakota digital 2 MSD's still can't get it to work. Also I need to input my wideband to the haltech so I can make proper datalogs Posted from my phone, I hope it works.

dat280z Posted March 22, 2013 Share Posted March 22, 2013 What are your a/f at top end? Sounds like it's leaning out on the top end... It makes some pretty good power for a bad tune lol Quote Link to comment Share on other sites More sharing options...
big-phil Posted March 22, 2013 Author Share Posted March 22, 2013 11.1-11.6 at the top. The more I'm playing with timing, I'm having to ad a little fuel to keep under 12 Quote Link to comment Share on other sites More sharing options...
ZT-R Posted March 22, 2013 Share Posted March 22, 2013 (edited) What are your turbine specs on the gt35 snail? Edited March 22, 2013 by ZT-R Quote Link to comment Share on other sites More sharing options...
dat280z Posted March 22, 2013 Share Posted March 22, 2013 That's way lean! Anything after 15lbs of boost, it should be in the 10s. Quote Link to comment Share on other sites More sharing options...
Chemicalblue Posted March 22, 2013 Share Posted March 22, 2013 That's way lean! Anything after 15lbs of boost, it should be in the 10s. Why? I tune most L28s and RBs at 11.5 to be safe. Quote Link to comment Share on other sites More sharing options...

Yeah, 11.5 and it's up to your timing after that. 10 is just wasting fuel. Quote Link to comment Share on other sites More sharing options...
big-phil Posted March 22, 2013 Author Share Posted March 22, 2013 (edited) Yeah 11.5 is spot on, gt35r has the .82 hot side, duel ball bearing....that's about all I know or can remember lol Since that video I am now at 18° With an AFR of about 11.5 to 11.8 at WOT. It's just hard to tune the extreme top end on the street so I don't notice I have much of a problem until I strap it to the dyno Edited March 22, 2013 by big-phil Quote Link to comment Share on other sites More sharing options...
dat280z Posted March 22, 2013 Share Posted March 22, 2013 Really? That's different... But If you guys say so, I believe you. It's just weird how it puffs white smoke at higher rpms which it' could be a sign of lean a/f. Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted March 22, 2013 Share Posted March 22, 2013 What size injectors you have, and what max duty cycle did you hit at that level Phil? Quote Link to comment Share on other sites More sharing options...
dat280z Posted March 23, 2013 Share Posted March 23, 2013 What size injectors you have, and what max duty cycle did you hit at that level Phil? That's a good question. Also what's your fuel pressure? Quote Link to comment Share on other sites More sharing options...
ZT-R Posted March 23, 2013 Share Posted March 23, 2013 .82 on a 30.... im making 510 at 11psi without timing, but im on a t04z 1.00 divided housing. Quote Link to comment Share on other sites More sharing options...
big-phil Posted March 23, 2013 Author Share Posted March 23, 2013 39-40lbs fuel at idle, I think it was 55-56lbs at full boost Quote Link to comment Share on other sites More sharing options...

It was super hot and overheated at that point Quote Link to comment Share on other sites More sharing options...
sq_creations Posted March 25, 2013 Share Posted March 25, 2013 Have you varified with a timing light that the actual timing at the engine matchs the timing on the haltech. I have tuned alot of cars and the glowing exhaust and falling on its face up top tells me the timing is extremely retarted or the cams are out of phase.

ZT-R Posted March 25, 2013 Share Posted March 25, 2013 I agree, you shouldnt be glowing at this stage... Quote Link to comment Share on other sites More sharing options...
