Dynoed again and wasted...
my money on the Technosquare ECU. It gained absolutely nothing through the RPM band and only a couple hp top end from were they leaned the car from 12.0 to 13.0 a/f. I have 14 days to send the ECU back and get the stock program reflashed and I think I will go that route. Although the raised rev limiter is nice its not that efficient for the 3.5's and our ****ty manifold. So it seems I paid $550 counting shipping for no HP gain throughout the curve and no torque gain at all. I was so ****ed I left the shop and didn't get the files but I will get them e-mailed to me soon. Im puzzled on what to do. My previous runs before the TS ECU were 226whp and 228whp without the air filter. Todays runs with the ECU were 226whp and like 233whp without the air filter which I dont consider daily driving characteristics but possibly something I would do at the track.
Well guys there you have it. I talked with Danny @ TS and I have 14 days to return it and get refunded. He said I should try 1 step colder plugs but i just don't see that helping performance. Is TS a joke with this reflash in my eyes I can deal with a little hesitation and stock rev limiter and keep my $500 for an intake manifold project down the road. I just don't know wtf to do.

Damn, this really bums me out. This was going to be my next mod. Do you think the TS flash would be worth it if my dyno shows me running really rich? Or would a Greddy E-Manage or SAFC II be a better route.
I have to ask, how many VQ35's of any make Maxima, Altima, G35, 350Z) have shown a real HP gain with the TS Flash? I know I read many forums with these vehicles and I don't remember more than a handful that have had a significant HP gain.

only gains I saw posted were from TS themselves....I dont remember reading any thread that an actual org user got real gains
sorry bout that matt, but hey at least he accepts returns...any restocking fee or the like??
if anything the most u'll lose is the dyno fee, which aint cheap but it aint $500 either

Matt,
That's definately NOT what I expected to hear. It's great that you're getting a refund and all, but this is very disappointing from a perfomance/modding standpoint. Was TS able to provide any other insight (outside of suggesting colder plugs)?

He told me our cars are designed for everyday stop and go driving and not for performance. He suggested 1 step colder plugs b/c the cars performance has been boosted and its more for racing now so the stock heat range might not be up to the task. His for of proof to that was a guy with a G35 gained nothing on the dyno with the TS ECU but put in 1 step colder plugs and felt an increase on the butt dyno but no actual dyno proof 
. Now I know TS isn't a new company or new at what they do but for $500 for a raised rev limiter and removed speed limiter is quite steap. It might help for a stock car but modded its really not worth it. Im going to try my best to get to the track tonight and will have the dynos posted tomorrow when I come into work. I'm just puzzled at what to do know....I have 14 days to decide.

sorry to hear about the waste of money. However, do u feel maybe it could be that you are running a stock TS ecu program for a relatively stock maxima? Therefore not completely utilizing the different mods you have on your car? Did TS offer you a reason as to why you didn't gain any power?

Blu,
Send me your before/after files once you get the after PLEASE.
We need to get your, studmans, and E55AMG2s dynos overlaid:

Humm....I drove a stock Max with a TS ECU......and I felt the difference....Sorry to hear that Matt. I guess its not what I thought it was......Maybe it wakes up stock Maximas.....and it needs to be tuned for cars like ours that have Mods...

Not defending anything until we AT LEAST see the dyno, but from studmans' post, E55AMG2 gained 10whp in "a good portion of the power band", ie area under the curve, yet not really any change in "(tuned) peak numbers".
Being that you have a 6spd, you'll benefit from those extra RPM.
Autos may not find this mod useful UNLESS they shift manually.

Sorry to hear about this Matt. Honestly, sometimes I wonder if any of these mods we do are really making much of a difference at all. I mean I put all these mods on my car and I think my car is real powerful, but then I go to the dyno and I pull 227hp/231tq. Which is good, but not what I expected, then I go to the track and can only pull a 14.3@98. Good numbers again until I see that just this past week a fellow org member hits a 14.17 and 14.19 with a stock Maxima. Plus there's been numerous other stock and modded maxima's that have been right around my same time. I believe that if I knew then what I know now, I would have done all the suspension mods, but not the engine mods. Anyway, that's just my 2 cents.

It's not funny, it's logic.
I mean, it all depends on the power/torque curve on when you should shift.
WE ARE NOT HONDUUUUHS, PEAK POWER DON'T MEAN ****.

i'm dying to see blu's dyno curves in relation to other TS guys that have gained hp/tq in the power band

With an extended rev limiter your only prolonging the shift points so that the next gear is landed in a stronger powerband. It doesn't neccesarily mean that the ECU is used to compensate to add MORE power after the original 6700 because that is more of a mechanical design: i.e. intake manifold, engine, etc. So the peak hp at 6700 for the VQ35DE is already surpassed. It can be maintained, but will obviously trail off
example: lets say a 4th gen with USIM hits 180 whp @ 6200 rpm and power starts dying out. With an extended rev limiter and tuned fuel maps, the customer cannot expect 190 whp @ 7000 rpm because the intake manifold is limiting high rpm breathing
Also, with the tuned fuel maps in the TS ecu, it does that job by smoothing out the dyno curve, adding up to a max of 10whp throughout the powerband.

Since Blu didn't get 240whp like he was *HOPING* for, I feel he may have been let down.
Once he posts the curves and we can compare, I'd like to see what happens.
PEAK number is all we have right now. What if it held HP/TQ for longer? Put down 10whp under the curve in the midrange like AMG? He already said it helped response, so sounds like some torque down low was increased? AGAIN, peak numbers are VERY very hard to tell from, we shouldn't jump the gun YET.

Keep in mind that you *are* on a new tranny, and the new tranny might still be a bit "stiff". If you did your baseline on the new tranny also then fine. But if your baseline was on the old one then that's something to consider.
The leaner AFR shows that the "engine" should at least in theory be making more power, but due to variable parasitics of new vs old tranny it might be tough to get a good reading on. There are lots of variables on chassis dynos.

this is disappointing news..the only nissan tuner that was ever able to crack a nissan ECU with DYNO proven results was JWT.. I was going to get the TS ECU, but too many dynos showed no gains... I hope JWT cracks the 02+ ECUs..im sure the 3.5 motor in so many cars should make them do that...

Don't hold your breath.
Clark Steppler could care less about learning the new ECUs from what I've heard.

Ohh and guys I don't know if the ECU contributed to my trap speeds tonight but I was over 100mph hot lapping all night with full interior. My best being 100.95 on the last run of the night hot lapping from a run before about 2 mins before. I now know at the faster track I visit with the car gutted on slicks it will run some unbelievable times. My best time was only a 13.92 but again this was with full interior. Gutted it would have ran a few tenths better and picked up about a mph or maybe more. On slicks gutted tonight I could have ran a 13.5@102 easily without even cooling the car.
