what do you mean by "pretty lean"? how lean is it?

 

Not to badmouth Technosquare because they do very well at taking care of their customers and that's our biggest concern. The reason why we're even in business is because we are also consumers and we're tired of being treated poorly. But...

The basic flash style stuff doesn't work on Nissans. Not the new stuff anyway (02 and up). The Hitachi ECU that Nissan uses are intelligent. They adapt and learn. Also Nissan starts out with a pretty good tune. Where we see gains usually isn't in the Basic flash that we send, though it works on a fair percentage of cars because we start with over 250 base tunes depending on your year and mod list. We shine in the ability to log data and adjust the tune for your actual car. We don't have a money back guarantee because what we do actually works and is verifiable on any dyno (butt dynos generally also verify what we do).


Our system doesn't just work on 50% of the cars, or 80% of the cars out there. It works on 100% of the cars. Even if you're using something like the Fcon or AEM, your stock ECU remains in the car and the people using "full" stand alones use our product to set basic parameters on the stock ECU so that their tunes on the stand alones work better.


Our ETA on support for the HR motors is this summer. We're headlong in Ver2.0 updates and tweaking right now. As soon as that is completed then the work on HR support begins.

We have a company building a new website from the ground up so that we can get more information to customers and allow them to give more information to us. That site should go live within a few weeks and will be updated on a regular basis as to what ROMs we support and what vehicles we support. We will have a place to submit unsupported vehicles and input the ECU part number so that we can see where our customers need the most support and we can work on it. Version 2.0 needs to be completed first though.

 

not to be the bearer of bad news, but the technosquare reflash has been very succesful on the new cars (02-up). it was better before that when it was a whole new ecu, but the reflashes have been very nice. on the hr's the improvements are huge. its obviously not as good as a car to car tune, but if youre just looking to spend 550 and get a 10-15 hp gain throughout and a bunch of tq too (i gained from 10-25 wtq on my ts tune) then its really the ONLY option. the osiris is going to cost you more than the ts, especially after you pay for the dyno to log for the etunes. im not sure if youre trying to say that the TS ecu doesnt work because the ECU will self learn back from what TS flashes in, but if so that is certainly not what happens. they spend a lot of time working on the code and testing on cars to make sure the tune is right, then they lock it in as set values on the ECU, essentially replacing the stock map, so there is nothing for it to self-learn back to. the only car ive seen that didnt make a load of peak power, still made like 15wtq for 75+% of the powerband and over 10whp everywhere except peak where it only made 4 whp. certainly TS isnt the best option out there. if osiris was available for my car i would get it, but for someone not looking to spend over 700 for a tune then its really the only good option

 

+1. Since I have an 03 G35, my car is basically a redheaded step child because no one other than TS has broken the code for the ECU and made it work. I find it VERY interesting that the "others" say they can't break the early 03 code yet TS did it nearly 4 years ago I am basically forced to go with TS.

Anyways, I had a JWT ECU flash in my 96 VQ30 Maxima and it greatly leaned the A/F to 13.5:1 above 5000rpms, but I never experienced any issues with my VQ30 over 2.5 years of use and 200 1/4 mile passes.

 

yeah i have a TS with 7100 rpm, high timing and an afr of 13.5:1 and ive put a lot of passes and daily on it without a hint of trouble. at the same time, if there was a better option when i did it i probly would have done that. it seems like the consensus of lean here is waaaay more rich than the consensus of lean on other NA sites, including other vq35 sites

 

guys... never had to deal with technosquare but it's just me.. can't justify myself getting an "off the shelf" tune.. also if it's coming from a huge database of data... also if they have a huge database of dyno stuff...
it's still another car with a different tune.. that is the reason I'm breaking your ***** (actually also because I cannot justify a full loaded F-con pro or a motec solution)

I had my car tuned from one of your pro dealer... to verify with the "camera car" dyno after the tune I saved 2 seconds sharp stretching the full 3rd gear... 12 second from 2K rpm to 7K than 10...

that is what people were wondering about


thanks guys. :-)

 

You're not understanding what I've said or how tuning works on these ECU's.

There is no universal tune that works on all cars. You cannot make a tune that will gain performance on all cars with a Hitachi ECU. The flashes made by TS, Cobb, or even Uprev do not take away all the ability of the stock ECU to adjust itself. We can set new targets and remove a fair bit of the adjustment, but the ECU does what the ECU does.

The flash that they produce is equivalent to the base tune that we send out. We use that to get base information and adjust the tune to the car. The base tunes in a prebuilt flash may work for upwards of 30% of the vehicles out there but in no way can be expected to work on 100% of the vehicles. Hence the money back guarantee.

We offer the $400 mail in your ECU tune also, but only as a competitive price product to TS (you're stating you paid $550 for it which is $150 more than what we charge for a similar product). We suggest anyone looking for actual performance gains on their vehicle use the $700 system that comes with data logging and diagnostic tools along with the ability to eTune their car and adjust the base tunes to what their car actually requires.

You do not have to use a dyno to log for the eTunes. We require a few 0-60 pulls, that is all. So maybe $3-$4 in gas is all it effectively costs.

We don't currently have HR support but it will be available by the end of summer.

 

to me a good tune for the VQ is 14:1 in the <4000 band
13.5 4000-5500
13 5500-6500
12.5 6500 - > rev limiter

maybe I'm wrong.. and on top of that work with the timing.

 

This is why it's so rare for me to frequent the boards. Our customers love our product and quite a few of them are fairly knowledgeable about our products. I just come around every once in a while and make sure people don't have misconceptions about our product. Because someone elses product does something they expect ours is the same and it's really not.


Who did your tune? It's good to rep the Pro Tuners for a job well done

 

sorry, didnt realize what you were saying. i absolutely agree, this isnt a honda, so no hondata solution really works. i certainly agree that end user tuning is the best way to get the most out of your car.

 

this is basically what i meant. a lot of people are dipping into the 12's afr. i completely understand wanting to stay safe, but with the cooling of the vq35 heads its super safe to run a 13:1 afr out to redline. i made my best power running a flat 13.5 afr, but i understand a lot of people wanna feel more safe, for which i would suggest 13.2-13:1, which is REALLY safe. obviously if youre boosted or running a boatload of timing over stock then this isnt really true

 

Here is some info I got back on my First e-tune. I never really looked at it.

I have also add some info I have been working for Cipher.
My First e-tune info. This what it looked like after adding Berk HFC's before my e-tune.:

 

12.63 is the target???? wonder if there is a reason for that? ie: stock wbo2 reading richer than actual

 

It's cool, I just like to clear things up because some people don't have the time to read every post in every thread and I like to make sure customers are as best informed as possible.



It sounds like you have a pretty fair set up with your AFR's who does your testing and data logging?

 

Haha, sometimes the targets are really safe depending on octane, or location (cali gas is poop) and also the mod list. We have a few race tunes that are richer than that to keep the cylinders cool under heavy loads and extreme duress.

 

i do my testing and tuning/logging, typically i test on the strip, but go to the local dyno sometimes and just go with a couple maps to compare

 

Cool, alot of people forget how useful a couple trips at WOT down the 1/4 mile can be. The dyno isn't the only way to check your settings

 

if someone requested a more lean afr i would assume that you would have no problem sending it their way, so it seems like the rich afr is just a piece of mind for you and the customer both. i had the same thing with TS, it came at something like 12.9-13.1:1, although they didnt offer free etunes

 

not to mention a boatload more fun and typically cheaper. a win win in my book.

 

well the tune was done by Mark at SGP Racing in Houston. He did an outstanding job.

I took a video of a stretch in 3rd gear when I had HFC , plenum spacer, HKS true dual.
than a video when I added strup headers and TP to that config.. after the tune
and this video is the "result" is an overlap + antishake of "before and after"...
I took the videos in really similar road, fuel (full tank), external temp, car temp, humidity after several days of the mods to allow the ecu to adapt to the new parameters...(just to be sure she wasn't voiding the mods)
