Is that 332 on a stock exhaust and filter ?
lol no that's not the same car
this is the white one weve just sold which that graph is taken from.
That's running the usual goose type exhaust, uprated fuel pump, uprated clutch, Blitz induction & Boost controller
But other than that she is all stock, stock engine, re-circ valve, tmic, std ecu, std injectors and maf.
Everything sensor wise is functioning correctly and ignition/fuelling is spot on
And in terms of reliability.......if the engine is all good and safety margins are put in place then why would you want a car mapped at that level unless you want to throw money away, that's the point im trying to make here.
This car has now also done 4 trackdays at 1.45bar boost on a mines ecu which has an aggressive ignition map mid range but fuelling was still good which was indicated after removing spark plugs after trackdays and plug colour was spot on so it is proven that if setup correctly cars are reliable at this level, if anything at all had been wrong with fuelling then this car on a track all day would 100% have blown up.
Track driving is the ultimate test for an engine & transmission good mapping and so forth so if cars driven to its limit all day and your living above the 5k rpm for nigh on half hour intervals and you can drive your car back with no issues then you know she is pretty much spot on with everything you have done
The only safety margins we carried out prior when setting it up was using a 10w/60 synthetic oil for when things get ultra hot on track
Backing off base ignition timing
Ultraonic clean & check flow the injectors to make sure they are working to their optimum
Plus one other little thing I do which boosts ignition/spark slightly but keeping that to myself
The main thing you need is all ancillaries working correctly and a damned good engine to begin with which is very difficult to assess as you do not know if:
Oil pump is providing enough flow to all moving parts, oil galleries/pickup etc are all clear
Crank journals have hairline fractures.
Pistons that have likely gone through many heat cycles could have stress fractures around ringlands
Valves may be burnt or need lapping in, guides could be worn which will destroy new stem seals
Shim clearances clearances could be excessive & cams / rockers may be worn
All seals could be old and may well give up the ghost once you start upping the power as more power means higher temps
So as you see its not just a case of saying ''my mate said turn the boost up bro''
Theres an element of risk if all the things above are not as they should be, but assuming they are then there is absolutely no reason to have a car mapped at that level.
Anything over 340ish bhp then Yes custom mapping is needed as the ecu can not calculate the volume of air/fuel going into the cylinders as readings it receives are outside of the given parameters for certain sensors, so in short it guestimates! which is no good as you will end up with either rich or lean points throughout the rev /load range on the fuel cell part of the map which you can adjust to a degree with items such as Apexi safc fuel controllers and the like but they do not take the ignition load map into consideration so you are kind of covering an issue by tricking the sensors instead of remedying the issue correctly through a tailor made map.
Just thought it would be useful info to a few of you as many tuners will always try sell you a custom map (even to run a measly 1 bar of boost with claims of much higher mpg, more power etc etc)
So if you know no different then youll get your arses and wallet spanked when you have absolutely no need to.
The doubters will carry on doubting as they have been fed crap for years, that's their lookout lol
All im trying to do is help those out who know no different and minds are still open. This is not coming direct from myself (although ive suspected this for years) but from a world class tuner who's been in this game since before the group b days designing, engineering and mapping all kinds of race cars and I would not question one thing the man tells or teaches me and he has backed up my thoughts above having looked through certain maps on generically chipped and stock ecu's and gains we have achieved since getting involved in the tuning side of things, many of our customers have reverted back to stock ecu's after having maps installed which they certainly did not need and infact the main reasons for doing so are because of the claimed benefits being poor drivability, less power, bad fuel consumption (they are the lucky ones lol) unfortunately many cars we have in have already suffered the consequences of a piss poor map by having engines blown, which is good for us I suppose but not so good for the average Jaoe in the street with limited funds.
Ask yourself this question people...............Why would I share this info?
When I could so easily take all your monies and just say ''well sorry sir but you will require one of our custom tailored maps on the latest all singing & dancing ecu'' which will cost you £xxxx amount
Then il grab more money from you with all the added extras such as Engine rebuild, gearbox rebuild, performance clutch, latest turbo, manifold etc and if you don't go for it all at the start then who cares! if your engine goes kabooom chances are il still get the job anyway so its a win win situation all round
We still do a large number of Pulsars as most people realise that I/we are genuine and true car enthusiasts.
We do a lot of other cars too both mainstream & performance so have absolutely no need to grab work by making false claims and flogging you stuff you really do not need! So in short if we say its needed then you can bet your bottom dollar that yes you do need it.
Purpose of this little rant is that no matter who does what to your car ''don't be a sheep and get mugged off'' do your homework and do not believe all the rubbish you hear on forums as a large percentage of it is just crap.
