Phunk can tune a car, that's pretty obvious...

 

Idle with my 1000cc injectors was pretty steady... typically idle would float around 14.0 - 14.9 ... so it had its range of travel, but it was not jumping back and fourth quickly... it would just sorta float around. I was not running any true closed loop cycle, so it was going straight off my fuel maps. On rare occasions I would catch it idling at a mid 13... probably related to correction maps... my correction maps (air intake temp, water temp, etc etc) were all from an older base map that was intended for much smaller injectors... while i did change the scaling on them to reduce their exagerated effects on the larger 1000cc injector, there was probably more work to be done on part of the tune. Very small changes in pulsewidth at low rpm with an injector that big as dramatic and exagerated effects on the A/F ratio while idling.

Also, these peak and hold 1000cc injectors are rated with very low resistence. Thanks to the FCON V Pros ability to support this type of injector without using such methods as inline ballist resisters to prevent toasting the injector drivers... i am able to get these injectors to fire with minimul pulsewidth... as low as 2.3ms according to the PowerWriter software. I typically get a steady fire out of them... I was not able to get anywhere near that with the very same injectors in my Honda Civic with AEM EMS and ballist resisters... which ultimately resulted in the AEM EMS being removed from the car.

With these injectors, I recommend an idle raise. If I had to rate the quality of my idle on a scale of 1/10... I would probably have to give it a 7... it was about equal to the idle of a Z with the Greddy turbo kit... an occasional little hiccup. I was at stock idle, and I believe that if I raised it up just a little I could have gotten it perfectly smooth... but then again I never even tried too hard to improve on it the way it was, because the idle was already very smooth and I didnt really plan on touching it until the car needed a retune, which never happened... my dyno graph showing the 467rwhp was on factory spark plugs with over 30,000 miles on them, and I never did foul them out.

Later on I did try replacing the plugs with a heat range cooler and I brought the gap down for honestly no good reason since I wasnt have any issues with the spark... but I lost measureable power and put the stock plugs back in. Had I been running on 93 octane rather then constant 100, I doubt I would have been running stock plugs.

I can tune a car yes... but there is always more to learn. Do not give me too much credit... this was only 9 psi... I mean... I took the STOCK GREDDY TUNE to 416rwhp with no mods other than a drop in walbro fuel pump. Then I put in a return fuel system and just had to do some midrange tuning and I leaned out the top end a little and made 435rwhp @7.5-8psi on the E-Manage... still on stock ignition timing with 100 octane. Left the car like that for several thousand miles. It takes little to no skill to map a piggyback fuel computer, any of you guys would do it... just remember I have a dyno and multiple wideband O2 sensors to watch... and I can run the car all I want as many runs as I want until the car is tuned just right... if you guys had the same access you would do just as well on the piggybacks.

As for the FCON tuning... still, I have only mapped it to 9psi so far. My engine never blew up because i feel my tune was conservative... running mid 11's at the leanest under boost, and considering the 100 octane... Well I could have run more timing... power was still raising rapidly with every degree I added, but after that 467rwhp I noted that I had already taken it much further than anyone else, and I had nothing to fall back on. Since then several people have made similar power and if my stock engine was still in the car I would be pushing it harder... but I was taking baby steps and then winter came and I yanked the engine.

Give it some time... anywhere from tommarow to 2 months from now somebody is gonna hit 500 on stock motor, and within a year someone is probably gonna hit 550 on stock motor, and its gonna go up. I build a lot of Toyota MR2s... in that community... well the MR2 stock piston is no better then the 350z, and the rods are hardly any beefier at all, with a 1.6 R:S ratio... and with only 4 cylinders guys have surpassed 500whp only to have problems with the stock MR2 oil pump. This community just has to tune around the higher compression.

I think you guys will be VERY VERY surprised how many 350z's will have HUGE *** power on stock engines once there are more cars with full standalones running around.

 

I know my car will be way slower than yours but I already cant wait till this summer. Can I please tag along one of these nights .....please...

 

Adam,
Have you already installed the blower on your car?????

 

Adam... of course your welcome to come out cruising!

 

Nope, waiting till spring. Nicer weather.

 

Awesome, hopefully I can finish the trio with some sort of FI in the spring...just can't decide which to go with.

 

I'll be there with you guys!

 

Sorry for the hijack, but what are u guys planning on getting?

 

Turbos...just don't know which kit yet..

 

I have a greddy tt kit on the way!

 

Nice! Any special set-up or just out of the box psi?

I feel left out with all the Chicago guys going FI this year

 

I can help you with that

 

As of right now just out of the box. We will see later on if I want to go with some sort of special set up.

Let Charles help you out with your problem!!

 

I also feel left out I need to start making the molla to keep up with you guys. Mcderns, will you be building the bottom end?

 

Nope, no bottom end or engine work will be done untill it goes. I wasnt really planning on going f/i, but I got such a good deal on the kit I coulnt pass it up!
