I own a baleno altura, cng fitted with lamda. Obviously the car struggles @ low rpm, it isn't fun to drive & i miss the petrol feel; the distance to be covered being so much that i cannot afford the luxury of petrol.
I've been reading a lot about TAP but have never exactly figured out what it does. Can please give me a detailed review/explanation. How much it costs?
Where from in south delhi? advantages/disadvantages?
I would be grateful
Additional info.
Car model-Baleno altura
cng-12/14kg(not sure) with lamda,
It's the kind where u accelerate to 4 rpm(ish) and cng switches on.
Engine malfunction light sometimes comes on around 70.
An advanced thankyou.This is a project i'm dying to undertake. Cheers

Due to the fact that natural gas has different thermodynamic properties from petrol, the timing must be modified in order to adapt the engine to CNG fuel . CNG is slow burner and has a very high octane rating of 110 as compared to 87 of petrol. A timing advance processor induces the ecu into advancing the timing by altering the MAP sensor signal which is used by ECU to determine the spark timing . All this results in much better driveability of CNG cars fitted with TAP. In my opinion both Lambda and TAP are necessary for CNG cars .

thankyou. Any idea about the following.
Cost?
comparison with petrol performance ?

In Delhi, it would cost around Rs. 2500.

My car (WagonR) has been installed with lambda and TAP since conversion - and the power /pickup is almost the same as in Petrol.

@Khandelwal- Thanku, where in delhi? Is your's a closed loop or an open loop system
How do you find out?

[arpandiv]

just a passing thought but has anyone tried connecting a TAP to a normal (petrol ) car and seeing if there is any difference in performance?

I doubt whether the same can be connected to a normal Petrol car. Its a kitted car's device.

As for the price / availability of TAP, the price varies from about Rs. 1K to Rs. 3K (Chinese / Italian). I suggest you opt for a decent one. As for availability, you can go to AA Transfuels at G T Road Industrial Area (near Nanak Piu Gurudwara). Its near Ashok Vihar in North Delhi. You can PM me for further details.

He is a very trusted fitter and my friend has got his three cars kitted from him. Delighted with the service experience and performance.

Lambda means closed loop. without lambda it is open loop. lambda takes input from the oxygen sensor ( lambda ) and the throttle position sensor to regulate the quantity of gas going into the engine intake thereby controlling the emission of the car . It has to be fitted by an expert since it has to initially programmed and properly calibrated.

Thanku all for your prompt replies.
@WanderNomad- I will pm u for details, if required. Thankyou.
I'll get the best one, money isn't a problem.
Another question, this improves fuel efficiency or the other way.

IMO, with Lambda, it becomes a closed loop.

Same here.
I have got my car converted from the same fitter. My vote goes out for him. Good experience and knowledge.

PM me for his number.

I have clocked more than 11K Km after CNG conversion.

My car's FE figures on CNG (per KG) are as below
Highways: ~22 KM (With AC) ~23 (w/o AC)
City: ~19KM (with/without AC)

Thankyou khandelwal. Which car is this?

Check my previous post - Its WagonR.

Does anyone in Mumbai/Delhi know where can I source Italian brand TAP's? Not the Chinese ones. Any help or contact details is highly appreciated.

bumping up this old thread:
From what i've noticed, most sequential kits, have a crank position based timing advancer and other cars with venturi based kits, have a TPS/MAP based timing advancer. Just wanted to know, if the TPS based module can be installed in a sequential kit car.
