no
would be more like 14 degrees at 3.2 bar absolute for a 7.2:1 @7500 rpm

I would say you meant 2 bar boost not absolute

LINCOLN

iTrader: (1)

That is why I asked as the map definately says manifold absolute pressure and start at 140mbar and finishes at 2600mbar.

Therefore the map is only for 1.6 bar boost or am I missing something?

LINCOLN

iTrader: (1)

Then again it is a basemap!!

Turbosystems

iTrader: (5)

what ecu is your base map from

LINCOLN

iTrader: (1)

Pectel T2.

Turbosystems

iTrader: (5)

so a base map not for a low comp yb

LINCOLN

iTrader: (1)

7.5:1

Edit - I did pass on the spec... stage 3 stuff with low comp (initially set up on a engine dyno - then increments to 500bhp).

Did not think 0.3 cr would have made huge difference but was wondering as 7dbtc was very low - hence the origianl question.

pa_sjo

You wouldn't map the car to run at 7 degrees, you'd have that in the higher load areas just incase you overboosted. It's a safety thing.. As per Mitsy, I ignored the absolute comment, as the figures are more suited to relative pressure.

pa sjo,

what is it you do for a living as you seem extrmeemly knowledgable and clued up? YOu in the tuning game or just a very competannt diy enthusiast?

It's just of personal interest to me

Did you / do you run nitros? For some reason, I always thought you did?

lincoln don't take this the wrong way but you seem very retarded ............................for your boost level,lol based on the small amount of info you have given us.we really need to see the whole map and it's multipliers

LINCOLN

iTrader: (1)

Nice one.

No global mutipliers (or adders)

Obviously there are ACT and water temp correctors.

I wanted to get the pectel going on my spare engine on an engine dyno, then change the inlet for rs500, turbo for t4, cams, ported cylinder head and then new bottom end. I just had too many variables and not enough experience but plenty of time and patience - after all it is a hobby.

As a base map to make the car start and run it looks perfectly good and lets face it, Ahmed is great at mapping so its unlikely to be anything other than what you asked for.

However, It would be dangerous to assume anything at all purely from the information you have given due to the immense number of additional maps present in the Pectel T series ECU's that can add or subtract from that map. For interest, i will try and BTTT a topic i did once all about such things...

I know that it is only a base map.

Just wanted to get thoughts from the pro's on it.

When i start tweaking it live just wanted to get an idea from you guys what to expect. I am going to be pretty worried about det which is why I wanted to get running on spare engine.

LINCOLN

iTrader: (1)

Thanks for the input Stu.

However, the T2 map that I have for ignition has only the above map and ACT (where 40 deg is zero) and Water temp adders (where above 50 deg is zero)

Nothing else to effect ignition.

pa_sjo

If you're worried about det, then listen for it!

LINCOLN

iTrader: (1)

Yes mate

Martin-Hadland

iTrader: (2)

There are plenty of igntion corrections in T2, here's ther global one..

LINCOLN

iTrader: (1)

By the time you have heard det you are too late.



My hack take on how i will blow up my spare engine...............

Take a base map.

Adjust fuel map for desired lambda.

Then adjust ignition timing for best torque.

The adjust fuel map to for the timing changes just made.

The adjust timing for best torque.

Repeat ad nausem and hope that the correctors that AB has already done a pretty close. The do seem to make sense with the physics.

LINCOLN

iTrader: (1)

Yes mate but not used in the map i have - only the ones I have listed.

I.E. - AB has not used any other ignition correctors apart from those already mentioned.

LINCOLN

iTrader: (1)

Just realised sorry for hijack!!

Stu can you clean this up?

Mike Rainbird

iTrader: (3)

Hi Linc,
Just spoken to Ahmed and he has advised me that he supplied this map as being for an absolutely bog standard car with no mods apart from 803 injectors and 3 bar MAP sensor with a designed peak boost of 1.5 bar .

It is in no way shape or form designed for anything else other than the above.

Turbosystems

iTrader: (5)

looks like a perfectly good safe base map for people to map their own engines

puddy

no mate,gas is fitted but I ain't used it yet as I was struggling for grip without it !

Very intresting stuff this mapping lark,but I paid a lot of money for some one else to do

mine !

puddy

Turbosystems

iTrader: (5)

i would be investigating your fuel system first and checking the pressure in your low pressure system and fitting the 3 mm jet as wes has suggested only because i told him before lol
I'd also like to see some pics of your tank in order to comment further

wes

Yes this is true, I know this because i got my swirl pot form you

Mark Shead

Puddy

Didnt you have MSD ignition system on the car and was it dyno'd with it,
I never let a car run hard if it has been mapped on the dyno unless I have live mapped it.

Mark

rapidcossie

Must have been something way off to have went so bad on the first extended period of WOT in the higher gears.

RickyLee53

Damn! You mean i've looked like a clown wearing DET can's for all this time when really if it was going to break before i heard it?

P.s. I know what DET sounds like

dovboy

fuel system would be the first thing to check before blaming the map.

pa_sjo

In all fairness though on a big power engine that's relatively on the edge, a nasty crack of det at 7500rpm can be enough to lose a piston without you even hearing it... but there'd have to be something seriously wrong with the spec or map for that to happen (or a failure, like a MAP sensor going).

PAUL V

Is it just me or are you all barking up the wrong tree ?
There is just 1 piston that has failed right ? well if it was the ignition map would not all 4 look the same ??? .

Now if the fuel injector was not flowing right would that not also cause the problem??

Puddy am i also right in saying you specked the engine had all the machine work done and built it yours self and gave it to Harvey to set up on his dyno for you ?

If this is the case and you have done 1000 miles on the engine then what are you pointing the finger at Harvey?

LINCOLN

iTrader: (1)

Something lost in translation then......

AB is horrible at returning correspondance (i.e. non-existant - but perhaps i have overstayed my welcome).

puddy

No.3 cyl is the worst,but all 4 pistons are damaged to an extent so I don't think its one

injector that is the problem.

As has been already said,it behaved perfectly on the road and I will be checking the fuel

system thoroughly when its back up and running.

I am not blaming harvey,but my 1 st thought was too much ignition as all the ring lands are

crushed,thus pinching the rings and burning the side of the piston.

I do use a digital 6 msd ignition on my car,but this can only be used to retard ignition ,such

as for nitrous applications.

Cheers for the positive thoughts,this ain't a witch hunt and I would happily use harvey and

ahmed again,but as mr shead says, with a full live mapping session afterwards.

puddy

pa_sjo

Did Harvey or AB advise you to get it checked in-car? Just out of interest.

puddy

No,but it was dyno'd a few years ago now,sat in the shell for quite a while whilst I plumbed

it,made and fitted the fuel system,and completely wired it .
