Apexi PFC and Scoob Mapping etc


Recommended Posts

<< Hi there i am looking to get this done (apexi power fc + commander)....how long have you been dealing in apexi and to be not rude but blunt are you any good at this and how many cars have you done.....

Right where do I start.

I am a software engineer by trade.. have been for the past 15years. I have specialised in air craft and have worked for Rolls Royce amoung others and have been part of teams doing engine management for aircraft engines, along with designing, coding / testing fuel computers and flight controls and missile control systems to a very high safety standard etc..

I got into Turbo cars in 1996 first with an MR2 and then in 1997 when two friends bought Impreza's.

I then bought my first Impreza in 2000, when they got annoyed with my borrowing and modifying theirs.

I used to run a Link ecu on my own car and remapped it through many incarnations of the car.

I then tried out an Apexi and GEMs.

I did a number of friends cars and I enjoyed doing it (I can look at a controller / laptop and wideband display and not feel sick) and they were all happy.

As the requests to map other cars started to come in I thought it was about time I started mapping for a fee as it were, and I have since mapped a large number of car, I have lost count, it kicked off in a big way tbh.

The following have been mapped very recently, I would hope they would be happy for you to ask them any questions.

The following are from Scoobynet and mapped on Apexi within the last two weeks - Chris DT, Peanuts, Flat4 which made 322bhp at 1.2bar.

I would like to think I am good at it.. I use a wideband which I fit to the car to monitor the fueling which I then map until it is correct, I use detcans to check for det and alter the timing to get the car as safe as possible with as much power as is safe..

As to other parts, no I only do Apexi stuff.. well I can get Link and GEMs but no cheaper than you can get it so doesn't make the proposition so attractive.

I understand your questions and this being the reason I am not charging a large premium to map them,

my own car currently is not a 1/4 monster, it is fast road car.. which now runs Apexi PFC and Apexi AVCR, and I have no advertising costs etc..

As said I am an active member on 22b, Scoobynet and here and would like to class myself as having a fair amount of knowledge of the cars I am mapping.

Thanks for the interest

Hi Guys,

yes it is indeed true I have had a Simon map.

We started out in Kent at Simons place and were off to scoobyshootout to do some more interesting stuff.

All was going well on the way up, mapped to 1.0bar easily enough on my new 18g.

Started to map up to 1.45bar and again it was all going well, in fact, we couldnt believe how fast it was for a humble UK face-icon-small-wink.gif

arrived at P20 SPD (Steven and Emma's place) and got suitably twisted.

woke up in the morning and Simon wanted to do some more work to the map, checking out where we could start to use some timing to great effect now the fuelling was spot on.

unfortunately I couldnt run as I had damaged the inlet pipe installing the new turbo and Simon warned me not to push it.

We managed a patch up to get us home and it was time for some more mapping.

woo yay!

tear assing from Yorkshire back to Kent using the full 1.45bar, through some tunnel and chasing a certain TVR for fun, and doing the business (all within legal speeds you understand).

the upshot is that Simon made me feel very safe while he was mapping, and I would definately use him again and recommend him to friends.

All the best guys

Simon. im doing a 2.5 build on mine in a few months time. I going to be running forged pistons, uprated con rods, uprated heads, custom turbo setup probably t4 hybrid, twin fuel pumps, reversed manifold and if I can suss it an eight injector rail, (2X4). Will you be able to set an Apexi ECU to run all this, looking at producing 500 Bhp plus with a 75 shot of progresive NOS. The car is mainly for drag strip use?

The Daddy,

Assuming the 8 injectors use normal ecu connections? each output twined?

the injectors being my only concern as it is a bu99er sometimes to set up large injectors and 8 of them will be worse still.. for you sanity and anyone mapping its sanity, you might do better going for 4 large injectors?

Mind you if it is drag only the idle is less of a problem, which is where the problem with injectors would lie if you fitted 8.

The Apexi is very capable and there is a version with launch control for drag racing etc.. but it is more expensive, called the Power FC Pro Spec (for DRAG) is has been designed for drag racing use. These units have two additional functions over the regular units:

1. Ignition cut used for rpm limiter - Regular Power FCs cut fuel feed when the preset revolution limit is reached. At high rpm, there is the possibility of knocking when the fuel is cut in high powered cars. The Power FC Pro Spec.CPUs cut ignition at the rpm limit to prevent the knocking that could potentially destroy the engine.

2. 0km/h rpm limiter setting - Allows for the setting for an initial rpm limiter that is active whilst the car is not in motion. This allows for mainting a rpm level for consistent launches.

You can email me at simon . roe @ generaldynamics.uk.com if you want to discuss further etc..

Mark,

the gains in peak power wont be huge, like Simon says a comfortable 270bhp, but what will be amazing is the area where that power is available.

A lot more useable power where you really want it.

I also found that the idling, closed loop running etc was better on the apexi than on OE ecu.

add a td05 (£200), fuel pump and regulator (£190) and avc-r (£250) to your list for nigh on 300 brake though face-icon-small-wink.gif

Daddy, Im sure you have a front entry TD05 fitted. I have a top entry on my 94wrx and although 340ish bhp is what most people rate this turbo at, there are a few people that have had approx 370-380bhp on this turbo!!face-icon-small-shocked.gif
