There isnt a definitive line of det / no det though as it can be a bit 'sparkley' which may well equate to the ~ 60 mark.

 

Thought as much Dunc - just trying to tie this down as much as poss.

Knowledge is power as they say... And when talking of potential det, serious moolah/hassle saving!

 

I did look at Vipec too recently Duncan, they were also not quite ready when the time came. Had to use a Motec on the 2.5 with a GT35/42R as seen in our other thread and on WR1OC.
Customer had more money than patience

 

I looked at ViPec - he had a version running on his own STi 2006 but not yet avail in uk

Also looked at Hydra but I didnt like the software - thought it was counter-intuitive.

Motec is the daddy but whoah at the price when you take AVCS, datalogging, DBW etc in the package price

 

Adzer - Going by your first post i'd guess you have a budget in mind???

I'm no mapper or expert but I have looked at the same options as you.

I'm guessing that you are kind of deciding between the Apexi PFC and the Simtek. (Around £1000 - £1200 budget??)

I currently have the Power FC fitted to mine at circa 400BHP but I also have an AVCR.
So by the time you factor those two costs together you are not far off the price of a Simtek. Add a couple hundred more and you can have the Simtek.
Its a change I'd like to make as it would allow me to have another fuel map.
Although I must admit the hand controler on the PFC is a great advantage. I constsntly look at it to see what max knock I have had after a run. Its also hand when diagnosing some problems.

There are other reasons to chose the simtek if you can strech the budget to it but basically -
2 fuel maps with Simtek only 1 with PFC
(although you can have 2 boost maps with the PFC if you also have an AVCR)
The Simtek gets rid of the MAF sensor
The Simtak allows you to add (at extra cost) Anti Lag and launch control.
(Although it wont be full blown launch control on your road car)

If money is no object and you want to have 4 full maps to swich between etc then Solaris seems to be flavour of the month. I believe thats what Wuz will be running. But that shows the level of motor that the Solaris would be used on.

Hope that helps a little.

 

yes it is not a definite number.. whilst mapping a known safe value on the knock reading is established in your example 11 therefore a value sensible is added to the CEL knock level to flash so if the car does det you will see the CEL flash.. I would expect on your car Andy det to register in the 30 or 40s and therefore at the standard 60 level you would drive on with it detting wihtout knowing.

Simon, I don't know if you remember me [mapped in late Aug/in Leicester LE3 area/you commented on how my silver WRX was like your other one/"worried about on-road mapping" then hooned afterwards! lol], but do you still have my map on your laptop? If so is it poss to consult it to find out what value the CEL is set to flash at?... Unless, of course, you can remember off the top of your head

PM/email if required...

 

yes I remember and yes I will check

 

Simon, you're a legend! ... Extremely grateful

 

set to 40.. from memory it was fairly quiet noise reading wise for an ej20g and only exceeded 40 when you bounced off the limiter lol.. you really should stop bouncing off that limiter.. do I sound like a broken record yet?

 

No, you've got me all wrong Simon lol.

I was only bouncing off the limiter because I was fiercely concentrating on not driving into the back of anything when we were mapping the upper reaches i.e. not concentrating on engine note/looking at tach. I'm a knackered 40-year-old - 'muti-tasking' is not on my horizon

IIRC, you set the rev limit to 7050rpm to save me from myself
