ok guys thanks for all the advice,

i have finally decided to go for RD ECU 0901. I think its safer than P&P and cam.
if i dont get desired results i can do these things and change the map according to new modds.
Now i just have to wait till Karthik launches the new ecu.
regards viky

RD is getting out a new ecu??
and by the way everytime you go for a new or reset map it is going to cost you.

1. Automech complete FFE

4. Tri-phase module
5. Yokohoma 195/50R15 tyres.
6. AutoGuage meter.

My car has clocked 38,800 km and now i am looking for some stage 2 mods like Fuel Pressure Regulator, ECU management system, Porting and Polishing, Enlarged throttle body, new injectors etc.

Gurus please advice me how to go about things so as to get best performance and what will it cost me.

I am more interested in low-end torque as i am not into any kind of drag or street racing but the car should be able to accelerate fast enough to overtake the likes of honda citys / lancers /baleno (all stock offcourse) easily .

i am ready to spend about 15-20k on the mods.


regards
viky
15 incher on esteem! please post some pics, I would like to know how the up-size performs , ride & handling VS comfort.
Do the tyers touch the wheel arches? when loaded/unloaded, on turns etc.

Nice mod list you have on the car best of luck with the rest of the mods.

+ 1 how did you manage that without any mods to the suspension?

Every remap after every added mod is going to cost you. Keep that in mind before factoring in just the initial costs.

Hi Viky,

Please let us know how the RD ecu performs. I also have a lightly modded Type 3 Esteem and am keen to do a bit more. I have been in touch with RD but they say another two months for the new version of the ECU.
I tend to agree with you about the ECU being "safer" than the P/P and cam. Better not to mess with the engine if you can avoid it - unless you are 200% sure of the guy doing the job.
Have you tried enlarging the throttle body?
Relatively cheap and seems to make a difference.

Regards,

SS

Hi Shrey,

Correct me if I'm wrong but reducing the weight of the flywheel would also reduce the torque produced???
I'm sure there would be a performance gain on the straight but how would the car perform on the ghats or with a full load?

Regards,

SS

Hi,

Whats your opinion on the tri-phase? did it really help ? I am trying to source a used one for my brother in India, who is using my car.
The online searches yield a scary review , some calling it a simple resistor in a fancy box, with an on/off switch . I think it was sold for over 15K and now used ones are available for as less as 6K (tbhp classifieds). I am still waiting for the price of the used one to go down a bit further.

Cheers

The tri-phase just meddles with the IAT sensor to report cooler temperatures to the ECU, which causes it to run richer, advance the ignition (depending on individual car ECUs) and produce a bit more power. Not to say that it's completely pointless or fake, but imo, you could do better by installing a real CAI.

As for the lighter flywheel, the car will gain and lose revs much more faster. It's useful in a racecar, not so much on a street-driven sedan.

You will still have a bottlenecked intake manifold and cams. The only way to see good gains is by cleaning up everything on the intake and exhaust side. That will involve a good intake, less restrictive intake manifold, a good porting job on the intake side, polished exhaust ports and and a well setup FFE with anti-reversion headers.

hi there,
the tri-phase did help me with the acceleration as i already had a FFE system installed. I will be removing the tri-phase unit as the ecu remap will take care of that function also.
15" tyres on esteem looks killer. will pics soon. yes the tyres scrape the inside of the body if you fully turn the steering. you just have to turn it in opposite direction a little bit. Suspension no problems as such.

It is going to take about a month more for the new RD ECU to be installed in my esteem as Karthik is still busy doing installations in bangalore.

So i was thinking about a FSE Fuel Pressure Regulator and enlarged throttle body.

Dragger is ready to do the throttle body modds if i can courier it to him.

Will the combination of FPR and enlarged throttle body increase acceleration/ low-mid end torque?
Can i install the FPR here itself in nashik or a expert tuner is required?
What kind of drop in FE i should be looking at.

The final stage will be the new Rd ECU

cheers

FPR can be a DIY job, no issues if you have proper instructions. The performance will be better than what you have now, with throttle body enlargement, acceleration will increase but not drastically.
The FE will drop by around 10-20% with these mods, again that depends on how you setup the FPR, and drive after the mods.

no alteration what so ever.
the ride is a bit stiff but the grip is awesome on dry and wet surface.

what do you think is FPR necessary or the throttle body will do the job as already i have a FFE setup and Wind filter installed .

With the Throttle body increase you will need more fuel to get a noticeable performance difference, so FPR will make a difference.
You can get the enlargement done and see if you like it, or not than go in for a FPR, get the adjustable FPR with a pressure gauge, so you can fiddle in the limits of your fuel system, stock system runs at around 35-42 PSI, you can safely go up to 55 PSI or a bit above.
Since you are running a FFE and a Air filter you are anyways going to be on a leaner side, with the throttle body enlarged the airflow will be increased and the engine will lean out further.So idle may be affected as well as the at high rpm the engine may lean out quit a bit and start heating.
BY the way what make tyres are you running, I am thinking of getting a set on My esteem.
