Hello
Where Is The IAT Sensor
Can Anybody Point Me In The Right Direction Please
Looking To Fit A Power Module
My Car Is A 94 WRX
Many Thanks

 

Dont fit a power module is my advice.... and to put it bluntly it's a piece of ****e that could cost you may £s in the future when the engine dies.

Plus MY94 does not have an IAT.

Tony.

 

Mods what are the chances of getting this made a sticky?


Whatever age scoob you've got(or any other car) DO NOT FIT ONE OF THESE! Its a cheap thermal resistor that confuses you're ECU into thinking its getting gobfulls of lovely cold air even when it isn't. This leads to Big over fuelling, Big bang, Big money in that order.

 

Thanks For That Info
Just As I Thought,Prob A Whole Load Of ****
I Wont Be Fitting It

Rolyatescort-

of course you have proof that the Power Module will make an engine produce a 'big bang'?

How many users do you know on here that have fitted one of our Power Modules and had any problems with their engines? We have sold between 200-300 for all models of the Impreza and haven't experienced any problems with engines going 'bang'. Please let me know as I am very interested. We have had one on our 2 test cars for a considerable amount of time now, one being a Skyline and haven't come across our engine going 'bang'.

Thank you.

 

Your engine may/may not be able to tolerate the extra ignition advance that this (loosely termed) 'modification' makes, depending also on other factors such as fuel octane.

It may/may not start suffering from detonation , which as you probably know, will grenade your engine within a short space of time.

IMO, this 'mod' should be avoided like the plague, if you value your engine....

 

Of course you have proof also? Or is this just some salemanship?

Firstly the 'Power Module's' that are usually discussed on this forum are 10-a-penny resistors that may or may not be housed in a shiny little plastic box that some poor sap has paid up to £20 for when it in reality can be had from Maplins for virtually nothing. It has been discussed a thousand times over on a thousand different forums that these Ebay specials and similar are junk, if you bother to search the net you will find several examples of people who have had pretty severe failures using these. If on the otherhand you have discovered some miraculous device that can safely up power for very little money (i'm assuming it costs very little as he's willing just to discard it as a piece of junk without question of getting a refund) that all us other power seekers have managed to miss out on then i'm sure we'd all be very interested to hear about it and i would happily apologise to the first person who could provide us all with proof of long-term sustained, reliable, safe power hikes.

Secondly, its a moot point as Tone Loc has already stated he doesn't even have an IAT!

 

He could have fitted it to the engine coolant temp sensor instead if there is no IAT sensor as it clearly reads on the fitting instructions that came with the packaging.

We have sold thousands of these modules over the last year and a half and haven't heard of any engine problems from our customers. Long term testing has also been carried out on our 2 test cars.

The modules basically work by advancing the timing by up to 2 degrees and then supplying more fuelling to compensate. This does not increase detonation (we have tested this on a stethoscope) and supplies just enough fuelling to not cause bore-wash. The end result is more power, particularly on an engine fitted with a turbo.

 

What a load of bollox... firstly the impreza runs far too rich as standard. When remapping the standard ecu i removed fuel.... i was hitting 10:1 AFRS as standard but now aim for something like 11.2:1. Are you seriously saying you think you get more power by adding fuel to a car already running nearly 9:1 AFRS

As for the addition of 2 degress... sorry but if you have to use the coolant temp sensor (all UK imprezas and pre97 JDMs) this will NOT add anything to the ignition timing. In fact some ecus such as the apexi would retard the ignition rather than advance. A great way to improve power.

Tony.

 

Have you got links to a before & after Dynograph as proof of power increases? There are many people on here (not me) who spend their lives tuning Subaru's and know absolutely everything there is to know about mapping, ECU's and the different sensors, yet amazingly not one of them has come to defend you or even agree with you in any way. Though one has given you a detailed, experienced answer as to why what you are doing can't work.

Hmmm, makes you think doesn't it?

Secondly in response to your above statement. Every car is different, this forum is testament to that. Why are so many people running knock-links, if you have the power to control fuelling so exactly (i.e. "supplies just enough fuelling not to cause bore-wash"). There are literally loads of examples of outwardly identical cars on this forum that react totally different to fuel, some imports can get away with just SUL, some have to use OB, some even just run UL. So how can you quote so adamantly and comprehensively that your mod "does not increase detonation" when just altering brand of SUL or even getting a 'bad' batch of SUL can cause det?
