ecu mapping etc
Discussion
just wondered what ecus most are running in there cars and what they are like?
ive got a 4.2ajp i havent even looked to see what ecu is fitted yet but ive heard that emerald are a common replacement.....what do people recommend either a chipped plug n play unit or fully mappable standalone?
im not looking for bags of power but something that gives a bit more torque and mid range grunt assuming that mine is a stock unit of course.

Odd question for a mechanic to ask.
not really lolask me anything with regard to a pulsar and il give you an answer, tvr's are all new to me!
one thing ive learnt over the years is that some things arent always black and white and different cars have different systems which work better on some vehicles than on others..... as said im new to the tvr thing so it always helps to get the general concensus before you go lashing out wasted dosh on stuff that may only be marginally better than stock and there are far more knowledgable people on the site than me when it comes to the cerb.

What was their reasoning behind this?
Joolz told me to do it before my re-map From a e-mail last year."TVR state 8thou inlet and 10thou exhaust for the claerances but I've found
that an extra 2 thou on them both improves tickover and low speed town
driving manners and helps the emissions test at MOT time a bit too. It
doesn't harm the top end power either. Sadly doing valve clearances is
expensive but if you were due a 12k service soon and the valve are
being done it's worthwhile having them opened up to 10thou and 12thou
to help the bottom end power".
Going to listen to his advice and go with this.

Before you decide what you are doing with your re-map and Valve clearance adjustments they can tie in. I have been told to open mine up 2 thou extra on both sides before i get my re-map. will help smooth the car out when re-mapped.
What was their reasoning behind this?if your running more power with a remapped ecu then cylinder temps may rise which could close the valves too much so kind of a safety net really which makes sense

I think it's more to do with actually getting the valves to close properly at low speed (hence saying it doesn't harm top end power) but it certainly won't hurt heat transfer into the seat.
I'd be interested to know long term effects on seat wear though.
You think wear will increase much doing this? I don't know enough about these engines to say eitherI'd be interested to know long term effects on seat wear though.
Extra clearance will create uncontrolled valve seating velocities as the valve stem becomes detached from the lobe early. The better the vale seating the more heat that will be transferred and so a burnt valve is even less likely.
There's a few running Emeralds, I have one on the shelf in my garage.
There are a lot with custom mapped cars from the likes of Jools, TVR Power, Austec unfortunately you need a re-writeable chip and all the gear to read and write them to remap the MBE due to them offsetting all the maps and making the hardware non live-mappable.
The latest craze is the Syvecs system that Charlie at SRR or Racing Green could help you with. Not much changed from £3k though.

mmmm! i know charlie as im often at the rollers there with the pulsars, funnily enough hes just sold a syveks to someone with a gtir i know. meant to be a great bit of kit but as you said not cheap lol
what are the emerald ecus like?
im only guessing here but would have said that mapping has got to be far easier with a n/a engine as power will be linear so cant see the point in running a very expensive ecu unless you have some kind of charger fitted....or am i missing something hence the thread.

Yes and no,
I think the main benefits with an ECU swap or re-map on these engines is mainly low speed driveability and a repair of the torque curve as TVR did such a shocking job in the first place.
Value for money I'd probably pitch it as follows.
1)MBE remap £400
2)Emerald £1500? fine tuned The latest K6 has a lot of new natty features.
3)Syvecs £3300? fine tuned
4)Motec £4000+++ not seen it done as yet.

Don't mean to be a pedant but I thought a remap was at least £600 + VAT? I think the main benefits with an ECU swap or re-map on these engines is mainly low speed driveability and a repair of the torque curve as TVR did such a shocking job in the first place.

Depends what you want doing.
jools will do a generic power and torque tweak for around the £3-£400 mark.
If you want more than that so low speed driveability etc improved then the price will increase.
Raceproved prices (Jools work), +VAT from March 2010. Suspect these may have gone up though.
Full re-map = £595
Just fuelling correction = £297.
Power Runs = £46.81 (I assume these are the ad-hoc type for willy waving ;-))
Short Induction Kits = £350
They also do cooling chips.

Hi Ridds .. I'm not at RP any more .. not been there for about 2 months. New project coming in January (based much further south for those who thought I was too "northern" ) 
If your still doing re-maps could you PM me your number and if you are can i get booked in for a re-map in the spring please.Cheers Scotty
