If your after more power just go over the top now as it will give you alot more headroom when say 550bhp isn't enough, but get ready for a big big spend. Personally I would sell your car and buy one that already has the power you want as it will save you thousands!

 

I was being deliberately simplistic, with the intention of stating the facts for clarity.
Not for the first time, you're trying to read deeply into something I've said, and getting the wrong end of the stick. If you desist from doing that, apologies won't be necessary.
For the record, I consider Steve to be a personal friend, and somebody we were and are happy to do business with. We have a cup on our premises with the legend "Steve S" emblazoned upon it, used on a number of occasions in the past, and ready for any future visit.

 

Best advice is go with ECU which will allow you run multi fuel maps(Methanol is nasty business,but more bhp worth extra messing) and this means,your OEM can run like Mafless,Multi fuel maps plus you will be not limited by boost,plus you can have LC and ALS

Second option is like Syvecs,AlcaTek or new almost forgotten SimTek Pro,which not sure if its available

What is best,that's the question for £1k,i would go with ECU with which your mapper will be most comfortable

Speak to your mapper and mainly speak with people who swapped their OEM ECU to the aftermarket ECU like SimTek or Syvecs,we are done this and we are went with Syvecs,if we are looking back NO,if extra £350-£500 is worth yes in my view

Best option would be to forge the engine first would it not???
Would have thought this heat will be affecting your power at the mo aswell

 

No need the 2litre sti newage engine is well proven into late 400s, I ran my own test mule at 503bhp for 30k miles with no issues.

Simon

 

Was that on standard internals then si?? Left u a message today will try again Tom :-)

 

yes 03sti.. oh sorry.. I had a mishap with the daily driver (drivers window shattered on the motorway) so handfrees kit useless as all I and any caller could hear was wind noise (from the now open window, not my ****).. therefore the phone was a redundant paper weight on the dash board of the car on my 3hour drive to and from a traders I was mapping at today (not that I have paper in the car needing weighing).

 

I normally cut them off at around 450bhp and recommend a stroker engine.

 

No problem mate :-)

 

my own engine I deliberately pushed.

got a few customers running at 480 something with no issues, but genrally advise 450..

Simon

 

If that's the case then why don't you just up the boost? Isn't Craig only running 1.55 bar on the 321T?

 

we can do that if we change the map sensor yes, but he will still benefit from an after market ecu at this stage

 

Simon mapped a newage engine for me on a rotated GT30, and it made 522.5bhp ran sweet for over 10k miles before I broke the car

 

I am going to get aftermarket ecu when money allows. Just got have a chat wi si about what's best for me as I not be tracking it so just for rd use

 

just tried calling you Craig

 

Yes mate in factory wi 12.30 be good to ring back??

 

of course

 

Stick with what your mapper suggests Craig!

 

I will do daz
Just can't afford that much yet unless a second hand one comes up cheap witch I very much doubt it

 

In a fast road car what benefits would the owner see using an aftermarket ECU over his OE ECU ?

 

To be honest I don't know???

 

A valid question Matty. I know of one person who dispensed with an aftermarket ECU and had a remap done on the standard ECU. This was on a rebuilt 2.1 stroker forged build (not Engine Tuner).

 

Mafless,switchable maps,higher boost without the going with aftermarket boost controller etc.

But those functions can have too on the OE ECU via CarBerry ROM(same which using A.Carr or other mappers)

Decision is on the OP


Jura

 

Exactly, functions on an OE ecu have come on leaps and bounds over the last couple of years.
I'm genuinely interested to know why an aftermarket ecu at circa 1K would be a viable option for a fast road car.

 

The only thing with the os one and oem ecu how longs it been out?? Is it tried and tested and can it compare to aftermarket ecu even though they ate 1k plus? Like I say I've not heard much about the os remap

 

Would love to see some thoughts from some mappers regarding this..

 

I typied and massive reply but my browse ate it.

The live map updates are a massive advantage when setting a car up.
On oe you make the change, turn engine off, load map, restart car, wait for cams to be enabled and the test the change. On high power cars it just makes the whole process overly awkward with 5minutes between changes when after market is live, you just alter the map and test it instantly.
The processors are faster and the maps have higher definition, car will drive smoother and generally make more power as a result.
Full multiple maps and an indication of which one you are on (not available on craigs car on oe).
I am comparing to alcatek, simtek, syvecs. Not all after market ecus are the same.

Simon

 

over 450? you are moving close to "almost" too fast for the road territory. I know my car scared the bajaysus out of me with big horsepower (but then I can't drive for toffee). if you are going to pump a serious wad of cash into your car you have to ask yourself what do I want the car, scary fast road, track, sprint, hill climb? or just to race 17 year old saxo vts, focus rs, golf gti, astra vxr drivers?

 

OS remap is very popular in USA and elsewhere too.Here is too,just ask people who have car mapped by numerous mappers like Graham@EngineMapper,Duncan@RaceDynamix,A.Carr@TeamCarr,Neil@Slowboy racing and many others.

This CarBerry ROM(which is modified GroupN ROM) has been tested in numerous cars and numerous people reported great results,please for more infos recommend like RomRaider forum,OpenECU forum and Nasioc.

If its safe,as every remap all depends on mapper and his skills and ability.

I jumped into my car last week for a drive and its getting soo far away from a normal road car. The constant noises and the smell of fuel and noises from all the fuel pumps.

It does have full trim and a dvd player so its ok If I could go back I would stick to a guaranteed safe 400bhp car
