Any 5.5 gen auto w/ TS ecu?
Anyone on here with a 5.5 gen auto got the technosquare ecu? I was wondering if the reflash helps at all. Recently ran w/ my boss's '92 NA 5speed 300zx from a 50mph roll and I wasnt impress w/ my max. I took off by a car but by ~90mph he caught up to my front fender and we both shut off. It felt like my 2k3 auto has NO top end and alomost lost to a STOCK VG30. I'm seriously considering the reflash. anyone w/ firsthand experience?
juice and blubyu both had it done. No gains were made for the auto. I might be worth getting the L-Spec version which raised the rev limiter and eliminates the speed limiter.

^^ really.....i thought kloogy really liked his?? so NO power gains for auto???? that is a shame seriously. and yea i think NA 300zx's are slower than they should be for some reason
Years ago I ran my friends 96 2 seater 5spd 300ZX at Phoenix International Raceway in my 93 SE-R with just Place Racing CAI, HS header, Greddy SP exhaust, and I would always whopp on him by 2-3 cars by the end of the 1/4. He would run 15.1s-15.4s stock and I would always get by him with 14.6-14.7s on street tires. He knew how to race n all, I'm sure my Max would slaughter a NA Z. My friend was so impressed with the SE-R, he bought 2 of them after that. Once a you drive one, you will understand.

But since it makes the redline higher, there would be more power at the wheels after an auto shift. WOULDN'T THERE?

ok i've seen dynos for stock 5th gen autos vq30 and on the ones i've seen the hp increases all the to redline so even in an auto with light mods you will see a power gain (atleast with the vq30 k ) if you increase your redline.

This is correct, unless you know how to tune engines

Mine is a 6spd though.
Also for track times:

Thats with a full spec TS ECU tuned for an intake and catback exhaust. As an auto I, like everyone else, would suggest you get the L-spec ECU. If you want to do fuel tuning get the SAFCII. If you want to do that and ignition timing get the greddy emanage or the SMT7.

SR20DEN, yeah I can send em to you sometime tonight.
Hmm problems advancing timing with those units? Would you be able to give detailed info as to whats up with that or perhaps point me in the right direction so that I can find it myself?

The SMT6 supposedly allows advancing timing unless you guys have heard otherwise....
eManage can only retard, since it's controlling the ignition OUTPUT and it can't guess before firing what the timing will be. SMTX intercept the INPUT to the ECU, ie crank/cam sensor, so it can fool the ECU into firing earlier/later as long as the ECU doesn't notice and throw codes.

From the TS website, the L spec is said to reduce the throttle flap closing during high rpm for increased power. I however find this to be hard to believe. Has it ever been proven to close?
I've heard of stories of other cars with TBW that the throttle is said to close slightly during shifts to make them smoother.
Has any of this been tested, and if so, proved to be true when upgrading to the TS l spec reflash?
I've called TS before regarding an ECU update, but they always ask for the modlist of my car and state to me that if not done with relation to my mods, the car will not run right, but E55 suggests that telling them that your car is untuned seems to be the best outcome.
I remember juice and Blubyu2k2 reporting that they saw no gain on the dyno or track whatsoever besides the rev limiter. And juice also states that he gets no better times when shifting at 7k or 6.5k.
I also remember reading where someone finally got TS to admit that they just used the same parameters as the 6spd version but for some reason couldn't get any gains on the auto from it, hence the offering of the L spec, and I also remember reading that some TS ECU's did not even have the rev-limiter option enabled when requested.
Another observation of mine is this : I have both a 4g and a 5.5g, when the 4g is in stock ECU mode, it seems to limit at about 6.6k, but pretty strictly around that area, as indicated from the tach, which I know sometimes tends to be off by a small margin, but still seems not to go past 6.6k. As opposed to my 5.5g which goes freely to ~6.8-6.9k, at first I was curious and thought, as I bought my car used, maybe it had a TS, but after much thought and consideration and after meeting the previous owner of the car, I finally ruled out that option(oh yeah i checked the ECU too, and no TS marking of any kind was found), as it would not go to the TS claimed 7.1k. My thoughts would be, does the 5.5g ECU let the revs go further before fuel cut, or is the tach off by a larger order as compared to the 4g?
Is the reflash really worth 365 dollars for only 300 more rpms because that's essentially what the gain is, from my POV.

my earlier dynos showed that at 6600rpm i was really at 6200-6300. In my dyno wiht the ECU I crank it out to 7000rpms on the tach and it shows up as 6700-6800 on the dyno. I have hit the rev limiter once and on the tach it showed about 7500rpm. So in conclusion the tach is off... atleast mine is.
youre not alone bgates.....alot of ppls are (mine is ~400 off).
I think blu and juice both told TS their modlist and neither showed gains. I told them I was stock and i picked up 9whp and 11 ft-lb. That suggests their tuning is not quite the best.
As for the extended limit, my times dropped due to the fact that I got past the 1-2 shift dead spot @40mph (shifts ~53mph). However the drops in time were about .2sec

Now that you have the rod bolts in, when are you going to get the L-spec program?

my stock tach is off for sure....I've hit 6800-6900 many times indicated on the tach till it bounces back....so i'm off by 200-300rpms...it's kind of cool though....i took my friend out for a drive with my APEX-i/BERK....and i told him to watch the tach swing passed 4k (VI kicks in)....then i pegged the needle all the way to 6900 or so and switch real quick....and he was like daaang that sounds crazy! and i told him....i have a raised rev limiter to 7500 and he believed me....lol
The limiting throttle theory has been proven, but what about on an auto, I would hope it would be the same outcome. But typically autos don't prove this, why?
Another observation of my 5.5 vs 4g is that even though it would be safe to downshift at a certain speed, it(5.5g) still insists on going with the next gear and noticeable limiting throttle opening which is characterized by a pretty large surge in power after the car has finished completing it's downshift, even though it had been WOT well before the downshift was initiated.
I know Juice has a picture of his dyno, I'm sure it's somewhere here, forgive me as I haven't looked around for it very thoroughly.
From what I've seen, what seems to be typical VQ35 output is to become a little wheasy at high rpms, despite the VIM as well as breathing mods, (I/H/E). Is this high RPM power loss directly linked to the Ethrottle limitations?
