Shiv had a outside company add features to Techtom that he flet were important to have for him to tune. He also spent the time for R&D and testing of a product fully before offering it to customers. He never bad mouth the product just informed people that are using the reflash system of the problems that have come up. Why would you think it would take Vishnu longer to offer the same system everyone else uses?? Because it's not quite the same. Yes it's based on techtom's hardware but there are alot of diffrence then what the public can buy.

shiv, thx for the explanation.

damn now i wonder if my autometer mechanical boost is reading correctly at high boost cuz mine is cheaper than nebolic's...LOL...

i know...i know...let's get back to the topic.

 

Eric,
I'm not doubting your statement but I rather hear it from Shiv about that....

Thanks for the quick reply thou...

 

Sure, what ever

 

nah i dont think the boost gauge is that bad (autometer) i mean i just want a general reading, not looking for specifics, if i wanted specifics i'd buy a more expensive unit, but as far as functionality goes, it does the job for a non techie. ytsejam, i think we are good to go, no probs.

hahah we'll talk more $hit at tap x on saturday.

 

Okay. Thanks Shiv.

Sean

 

oh here we go again with nebolic's trash talk...i know i know...i need a catback soon!

 

I for one would like to see dyno results from the xflash on a stock car on a regular dyno (like dynapack). as good as shiv's may be i'd like some normalized numbers to compare it to the dynoflash and P2.

 

Thwack, There is no such thing as "Normalized Numbers". Most of the dynos all differ in at least a little. The best comparison is to put both cars on the same dyno under the same conditions (temp, humidity, bar. pressure...). Only then can you get apples to apples comparison.

That is why I think that most attempts to quantify differences on these boards is fruitless. You can't really compare different dynoes, and 1/4 mile times are very dependant on driver ability.

I like the idea of test driving the different tuned cars, but this isn't very easy either.

Just an opinion from a non-tech.

 

well i have a news for u guys,
not to start a flame, but it's a kill story.

nebolic smoked an STi with MBC & Turboback earlier today by 1 car... xflash in action !
i didn't see it just heard the story

 

yeah, but most other dynos read pretty similar, whereas shivs tends to measure like 40 hp less than the rest. going off differencs in power from stock to flashed it seems that xflash raises like 20-25, as does p2, and dynoflash from 25 to 30... but is 20 hp increase on shivs dyno equal to 25 on any other dyno??

 

My dyno doesn't agree with this statement.

Shiv

 

Sounds like flame bait to me? For one, I never trashtalked Techtom or any other reflashing system. I observed a serious problem with a techtom-reflashed ECU and stated my finding. Findings that have been confirmed by Technosquare, the US importer of the Techtom equipment.

Now that that is out of the way, the Techntom "system" consists of some cables and DOS-based map editing software called Mighty Map. We use the software since it's already available and perfectly adequate for the job. But we made our own cables out of ECU connectors we had lying around

Like any other programming software language, simply having the program doesn't make you fluent in it. Although Techtom does get users up and running to a quick start by telling them where, in the ECU's hex code, to find the fuel, timing, boost taper, rev and boost limits tables. Of course, there are a few dozen other maps which aren't provided/translated and require actual digging/work to find. Once found, then one has to figure out (through what can only be called trial and error) what they represent and how they function. This is what took the extra time. And this is why the XFlash performs as it does.

shiv

Other than the fact that California's premium unleaded fuel is garbage, I truly envy you left coast folks. To be able to walk into Vishnu tuning and get Shiv to tune your car.. That'd be pretty cool.

As far as flashes go, I'm not going to focus on anything but the Xflash, so as not to create anymore thread drama.

I do want to tell you guys why I'm choosing an Xflash to replace my SAFC with, though.

1) Area under the curve. Someone mentioned that the Xflash tapers a lot (from 23psi to 18psi) to redline, whereas other flashes taper a psi or none. As stated, Shiv wants it to be that way. While it probably isn't safe to hold 23psi to redline at all, he's having it rise up there for a much stronger torque bump, then settle to very safe levels. Think of how useful that will be on a roadcourse or autox.. Or if you don;t do those things, think about if you get next to another car on the interstate. When you mash the pedal in and wick up to a safely tuned 23psi, I promise you're going to be pulling harder than if you were at 19psi. It doesn't take rocket science to make the turbo hold a set level of psi (19), any one of us can do it with a $40 Hallman manual boost controller. The Xflash is set to taper because that's how it gets the best power everywhere safely, and gets great area under the curve.

2) Shiv off the shelf tunes are "torture tested" (quote from the Vishnu site) for extreme conditions. This is for repeated pounding on the car that occurs in conditions like road racing. Drag racing is nowhere near as hard on the motor and turbo.. You run through the first four gears for 12 seconds, then its over. I like the fact that the guy who wrote my ECU map is looking out for me on my track time when I'm relentlessly pounding the car again and again accelerating and braking and accelerating again for a full session.

3) I can upgrade to an XEDEflash later. This part takes the cake and runs away from the party in my mind. I get all free updates I can add myself without pulling the ECU to send off to be reflashed again, and if I get some of my own parts, I can take the car to any AWD dyno with a wideband O2 and make adjustments myself. I have the full ability to use the maps that Shiv works hard on, but I can also forage off for other mods myself. That's freedom as well as support! The best part is I can start with the Xflash and decide if I want to do this later.

To me right now, there is no other choice for ECU upgrades because none is nearly as complete, vast, or controllable by the end user, which is you- the car's owner!
