[Richard 350z]

I reorganized the list of modifications on my 350Z, by type of mod. I'd like to use this as my signature, but it is awfully long. I could use a very small font. What do you think?

"TechnoSquare ECU - custom flash"

What does this do for you and the car? Just curious....maybe someday.

 

[Richard 350z]

You need the ECU flash if you have a lot of engine and breathing mods (exhuast, intake, cats, plenum, headers, etc.). The stock ECU setting are not optimal with all those mods, and you can run lean, which is dangerous for you engine.

Tadashi (owner of TechnoSquare) is a wizard at computer tuning. He remaps the fuel delivery for the specific mods you have. In addition the flash raises the rev limiter from the stock 6600 rpm to 7100 rpm, which is more reasonable. Finally, the flash removes the 156 mph speed governor. The car is capable of about 180 mph (although I have never had mine above 150 mph LOL).

Here's the Tilton clutch and flywheel:

"...front wheels 18 x 18.5..."?! Somethin funny 'bout that signature Mister...

& when was it you first noticed yourself moving past 'tricked out'?...

& Normally aspirated, to boot. Schweeet!

Hey lionkiller, this is a list from Richards signature on 350Z Motoring.com

I believe what you have on this sig: 18 x 18.5 is a small typo:

hey richard have you dynoed yet? if so what numbers have u been putting out.

 

[dublS4life]

thats ri- goddamn-diculous! * i wish i had that kind of mula! wat r ur dyno #s?

 

[Richard 350z]

Good catch. No, my wheels are not 18.5" wide. I fixed my sig. I did see a Caddilac Excalade EXT (? - the pick up version) with 26" wheels (!!!!) earlier this week at the shop that installed my Koyo radiator and Nismo thermostat.

Dynos are a very sore subject with me. When I started modding my 350Z almost a year ago, I posted my before and after dynos at the Evil Board, and got flamed so mercilessly that, eventually, it lead to my first banning there.

Here are the numbers, for whatever they are worth. I don't know what to believe. My baseline dyno bone stock on a Mustang Dynomometer was 233 rwhp. After installing the Cams, Headers, Exhaust, 14 lb. flywheel (since removed), Pulleys and Intake, I got 301 rwhp on the same Mustang Dyno. That's the number that got me into trouble.

Later, after adding the Hi-flow Cats, Plenum, and ECU flash, I went to a different machine -- a DynoJet, and got 276.5 rwhp. How I could lose 25 rwhp after adding more mods is beyond me. I will NEVER dyno again. What matters is how fast you can turn laps at the racetrack.

Since adding the Tilton Clutch and 8 lb. Flywheel, accelaration is better. It does not add any peak hp, but it adds up to 30 rwhp to the acceleration curve prior to reaching redline.
