Dear all.
I bought an an early PI back in December and would be interested to have member's thoughts on changing from mechanical fuel injection to electronic fuel injection.  The pro's and con's invloved and the best person to speak to regarding this.

Cheers

Hi Mick,

Depends what you are looking to achieve.  Perfectly possible to get decent results from PI but programmable FI systems usually include ignition management and barometric correction so you should be able to squeeze very decent mpg out of it and have it behave in the high Alps.  Also, if running a non-standard engine it'll be far easier to tune to match.

http://www.club.triumph.org.uk/cgi-bin/forum10/Blah.pl?m-1286652768/s-165/  froms Posts 176 - 210 contain most of the FI stuff.  There's a similar thread on Sideways Tech too.

Here's a TR6 (repatriated from the USA) that I helped a mate with a few years back

Goes well.....

Nick

Hi,
I had PI on my Spit/Gt6 2.5.
137MPH on Autobahn.
30's MPG normal driving.
Lucas (Prince of darkness), killed my engine.

Now I have EFI (Alpha N) and 20's MPG.

If your PI is running sweet; keep it.

I would not go back to PI as EFI should be better....For me it was not.

Cheers,
Iain.

Hi Mick,

I have just gone from a Lucas PI (with Bosch fuel pump), on a tuned TR6, to Emerald EFI system, with Jenvey throttle bodies, adjustable (in length) trumpets, wide band Lambda probe, 3 way map switch and AFR gauge.  

Pros:-

1. Overall better starting - hot and cold.
2. More torque.
3. Better throttle response.
4. Improved MPG.
5. Engine flexibility.


Cons:
1. Cost.
2. Slight loss of character.
3. Slightly less 'meaty' exhaust note (more refined).



In terms of outright power, there is probably little difference in it, but improvement from idle to 6500RPM is noticeable, and engine will feel more energetic. The Lucas system is actually very good AND reliable. I have ran the original, bur rebuilt system for many years on both standard and tuned TR6s.

There are quite a lot of features and adjustments with the Emerald K6 ECU, perhaps like others on the market (like having the ability to have one of the map settings, pop, crackle and produce flames on the overrun I have covered 3000 miles so far, without any issues.

If you need to discuss further, or want pictures, please do send me your e-mail address.



Good luck.

Hello Tom
My email is mick@theploughatleigh.com.
Did you do the work yourself, if not who did it and yes any pics would be great.  I am still thinking about what to do.  
Thanks for your help.

Cheers

Mick,
I race my Vitesse on Lucas Pi, and it satisfies me, if not the timekeepers, but that's me, not the car.
Pi is notoriously rich at anything other than full throttle because it goes a bit lean then otherwise, so maybe EFI better economy
Tom's better throttle response and flexibility are so subjective - Tom, can you substantiate 'more torque'?  Rolling roaded?

And you had better be sitting down when you learn the cost of Jenveys and all the rest of the kit!

Hi Mick,

Will send something over shortly.

Hi John D,

Car is yet to be test on the same RR, for true back to back testing.  Will keep you fully appraised.


Cheers.

There is also a programmable box that some of the TR guys swear by. I will remember the make eventually. Might be a Stealth Black Box.

You just lock the weights in the dizzy and program up the box.

The 123Tune is also very easy to program. Uses standard Bosch cap and rotor arm so easy servicing.

Cheers

The 123 offers two - yes, TWO! - dizzie curves!

That's not mapping!  Megajolt offers 10x10 mapping points!   I think it's 10! x10! possible curves, or 1.3 x 10^13.
More than needed, possibly.


The 123 is intended for unusual engines, for which the owner can't find and original dizzie.
What is the box that TR owners swear by?  Not a "MegaJolt" is it?
