Really? I've seen some very powerful setups (meaning 300+ whp from a 1.6 which puts out 115 hp stock) which have been done with nothing more than an e-manage, bigger injectors & other related hardware. No standalone in sight anywhere. However, a standalone will definitely be better, its just that standalone is not the "only way".

Dyno tuning helps get an excellent tune that's 100% optimized, but one can get close to that without the use of one. People have tuned by ear for years together, its only now that you get nice tools like wideband and EGT to aid in tuning.

Please share your experience with dyno tuning. Tell us more about how its done "professionally".

I doubt it. The smallest dynojet can measure up to 1500 hp. Even some of their older models could measure a minimum of 1000 hp.

Also piggybacks are a good option if you want to continue running the car's OEM electronics network, running through the car. The OEM ECM's control an awful lot of functions these days.

PS: I agree that having a dyno is beneficial but dont tell me cars havent / arent being tuned without dyno's and are still performing well?

I agree with u bout the normal boosts levels like the 4-7 u can use a piggy back.....but i am talking about the proper setups......well one more thing is yea i know almost everyone tunes according to the experience coz india i guess is just having one dyno.......so wat i meant by my statement is u can tune either u need the car for months with the tuner or still can tune your car which is running just fine but is not optimized....opmization was my point sir....

PS:- Hey Psycho i know ur esteem is running gr8 but can experiment with your tuning sir but not a lehman can do that hehehe

This is the exact kind of misinformation we don't need spread around. If you talking about SAFC and other basic piggybacks then yeah. They arent capable of controlling a turbo setup. But an e-manage is a totally different animal. So is an Xede. These are much better solutions and people have run 15+ psi all day long without breaking a sweat.

[archerdyal]

Yes i am exactly talking bout SAFC and Apexi neo..........but i dont think so to run e-manage at high boost i mean you are producing 50% more power or maybe more and still u think its possible with e mange well if u have done that or seen thats very good....but i dun think so stock ecu will not be able to handle the pulse width of big injectors...i am talking about big injectors because you need them at 15 pounds of boost......

They can do that if they use the Diesel Internals.. LOLz

I don't THINK so, I KNOW so. You can think all you want, its been done, I've seen it being done and there are ways to do it. For starters, go read the book on turbocharging by Corky Bell.

Turbo tuning is not for laymen.

Can do it with the right injectors and eManage with the basic wiring harness (depends on the model of the car too.) Please read this as 7-8 psi.

True

Please do not forget the compression coz the fuelling octane depends on that. (Octane rating depends on the dynamic compression that the car runs)

Dude there is at least 1 car i know of that is running a little close to 1 bar of boost, and if you want to know why that car did run the mumbai sr at half the boost it was set up to run was cos the fuel pump had packed up and would lean out after a specfic band and was fixed track side, and yes it was not the most reliable of car but of all the turbo cars i know abt it has been the most reliable and is also being used as a daily drive to date, yes after almost close to a year of running there seems to be a problem with the wastegate and as all turbo cars it does eat on the clutch....
Well now from the same team there is also a 1.0l turbo too, which i heard is really quick but there is still work to be completed on it.,

Have you seen these installs and tuning being done outside India.... then yes thats the way to go cos roadside tuning is ILLEGAL, but in India there is no such rule so it is done the crude way, as i have see some tuners do it without a dyno can get as close to 90% perfection and the SR results speak for them....
Well agreed with what every one says stock ecu's may not be re-mapped but the easiest and cheapest add-on to the computer is getting a piggy-back like a emanage blue/emanage untimate, hondata etc.... If u closely look at all the sites they say a piggy-back is a required upgrade(for bolt on kits mostly stock) but Stand alone is a ultimate upgrade........... Completely agree with what Psycho say reguarding the right kind of injector upsizing and setting up of the fuel and ignition maps using the right set of tools.
I know the emanage blue is capable of holding 1bar or more of boost with no problems if all the wiring is done.
Emanage blue connected through the universal wiring harness from greddy in an Esteem and Zen both turboed.... no problem...

Hey memo,Psycho,
Yeah you could be right about e manage but i am talking about high end jobs because the thread was for the best so best will be high money=More power.....i am talking about dynos here because the figures and the quality the tuner gets.............. its simply a aid to the tuner what say...

PS:-I live in california and this state has the most strict laws but still i find so many cars with custom turbo jobs and high end modding

YES buddy i know all abt Cali have been there, I am presently in Denver and i am also in to the modding thingy(doing a degree on the same), both here and back home in Bangalore..... Yes agree with you the dyno is the best way to tune, but there are some ppl i know who can tune cars without a dyno and there results are reconized too....
Well as far as I know there is only one dyno that is finally approchable to the public and the other two are factory owned, well considering the fact that I am from Bangalore do u think i would go all the way to Mumbai just to dyno my car i would be spending more than i am asking for just to tune the car when i know somebody who can set it to 90% state of tune with the right set of tools.
With the right set of tools i am reffering to the high end computer technology like the emanage bundle software where u now get data logging both on standing and running and other such software bundles that plug to your compand the car's ob2 port, and also the use of wideband o2 sensor and scanner and data mapping kits which let you know instant afr and lamda values and the logging can be broken in to in milliseconds... and with these tools say u can approx set a 90% state of tune for your performance mods and as a tumb rule approx the bhp on the crank and abt 20-25% will be the bhp rating on the wheels.....
Well reguarding the ecu thing pls look up the emanage site for the mods you can do throught the emanage ultimate, the piggy back that you can consider to be a standalone, and yes I do use one on my car and it does let you tune to a really good extent from fule and ignition maps to shift managment for triptronic shifts... By the way there are a bunch of piggy backs that let you do a lot more that what they are capable of doing..... Well as you are in the US of A, you probably know of the loads of fedral and state restrictions......

Oh! I hope you are completely aware of the fact that the car you are talking about also had a problem with the head (which was certainly not a minor issue)? Like I said earlier, not everything you hear is the truth (specially since you haven't been around to witness things). Or the entire truth hardly ever comes out. This applies to MOST tuners. Not trying to pin point at anyone.

Also, how many turbo cars have you seen running in India apart from the one you seem to so well know about?

Sorry this is not going to be pointed at you but is going to be generic. What I do with my car is my problem. Let me clear a few things once and for all on this forum:

1) I am not a tuner: I work for a software company and Vasu a good friend and mech helps me with my builds.

2) Yes I run over 12 PSI if I go on a full throttle but that I hardly ever do.

3) Yes there have been problems with my car and no car gets through a tuning round with it being 100% bang on.

4) Yes my head has been damaged on a couple of occasions but never irrerepairable the last time was mentioned online. However yes I changed my head (nothing turned out to be wrong with it) but the problems root cause lay with my water pump failing. Now mechanicals are out of my hands as I do not manufacture parts.

5) I do not wish to know what the other cars run I am happy with what I have. Hence my car my business so please lay off all of you who have problems with it.

I came on to this forum as a newbie myself to cars and and lived here as an enthusiast and would love to continue to do so without indirect personal attacks. So please let us all share our learnings rather than picking on flaws all the time. This is a place where we come together to form a community not as a nitpicking group. So please let us all enjoy our stay here.
