Mafless Rampiing by Andrew Carr on OEM ECU ;) - Running times now on post

Hi Guys,


Right BOYS AND GIRLS!!!

Who wants a Stock ecu remapped - MAFLESS with ANTI LAG , Duel FUEL Maps !!!!!!!!! and MORE!!!!!

Its now available by Andrew Carr - Team Carr.NET no Licence just mapping with a NEW mapping option.!!!

32bit ecus will be available soon

Here are some details of the ROM file I have been developing for all MY01-05 WRX and STi ECUs. I hope this answers most of the questions anyone may have regarding this new capability. I have put a lot of time and effort into testing this setup and would not be offering it unless I was completely satisfied that it was suitable for general use. I have still to verify all the compatibility issues especially with WRX ECUs but this will be done this week hopefully.

Initial pricing will be £320 plus parts, I intend to offer package prices including all sensors and switches, these are still TBC but I am aiming at around £450 including 3 or 4Bar MAP sensor, AIT sensor, clutch and feature switches.

Essential Features
==============
* Speed Density instead of MAF based (see note 1)
* Retains all OEM features - Start, Idle, Knock Control, Closed-Loop Fuelling, CEL functions.
* Flash Check Engine Light in the event of ECU applying knock control.
* Per Gear Wastegate and Boost Target compensation.
* Target Boost and Overboost fuel cut maximums increased to 4bar absolute (see note 2)

Additional Features
==============
+ 2 full maps (Fuelling, Ignition Timing, Boost Control and AVCS) selectable via switch at any time.
+ GpN Style Anti-Lag enabled/disabled via switch, throttle kicker support including rotational idle (see note 3)
+ Launch Control - optionally enabled/disabled via switch
+ Intelligent Flat Foot Shift (see note 4)

Notes
====
1. AIT Sensor - Speed Density systems uses Manifold Pressure, Engine Speed and Air Temp instead of Mass Air Flow to calculate fuelling and ignition timing, whilst it is possible to use the IAT sensor built into the OEM MAF it is better to replace this with a Charge Temp sensor somewhere between the intercooler and throttlebody, if you wish to remove the MAF housing completely then this is essential.

2. MAP sensor - Unlike the standard ECU where the MAP sensor is essentially only used for boost control and overboost fuelcut, in a speed density ECU it is absolutely essential that accurate Manifold Pressure is measured and the limits of the MAP sensor and/or ECU are not exceeded. The standard ECU is limited by software to only read manifold pressure to 2.72bar absolute and the actual MAP sensor fitted on top of the Inlet manifold only reads linearly to either 2.5bara (Pink Label) or 2.8bara (Blue Label), additionally there are limitations on the use of aftermarket MAP sensors, for example a GM 3Bar sensor can't be configured to read lower pressures (ie vacuum) correctly and will result in a 1200-1300RPM idle speed!
This new ROM overcomes all these issues by allowing the ECU to read manifold pressure and control boost to 4bar absolute and use virtually any 0-5v MAP sensor. I have thus far verified the following sensors:
- OEM Pink Label (2.5Bara)
- OEM Blue Label (2.8Bara)
- OEM Hawkeye (3Bara)
- 3.5Bar AEM
- 3Bar GM
(3Bar and 4Bar OmniPower sensors are awaiting testing)

3. Everyone loves antilag However, this implementation isn't just pops and bangs, it generates a lot of additional heat in the exhaust and can damage turbos, also remember that all MY01-05 EDM and MY01/02 JDM cars have an oxygen sensor and possibly an EGT sensor in the exhaust manifold which ALS could easily damage. The solution is to move the Lambda (and possibly EGT) sensor to the top of the downpipe. I will NOT activate ALS on any car that still has sensors pre-turbo.

4. Flat-Foot-Shift or No-Lift-To-Shift allows you to hold the throttle open whilst changing gear gear with the ECU taking care of reducing the engine speed rather than running away to the rev limit. In this setup the ECU 'knows' the gear ratios and current gear allowing it to calculate the correct RPM for a seemless change into the next gear, again it uses quite aggressive fuel and ignition cutting techniques to achive this. Holding the throttle open during gear changes is similar to launch control in that sufficient gas flow and exhaust temp can be maintained to keep the turbo spinning, resulting in less lag. A clutch pedal or gearstick pressure switch is required for this to work correctly, the easiest solution is to use the clutch switch from a later DBW car as these bolt directly into the MY01-05 clutch pedal assembly.



Prices for group bookings will be less, supply of your own switchs will be even less..

Happy reading


Thursday

AndyG - Ill be here

Friday

The Car Man 9.00Am arrival please

Mark - 12.00 Lunch time arrival please

Gary Blake - 2.30 arrival please

Saturday

Owen Clarky 9.00 arrival please to you time to sort the bits

Travis 12.30 arrival please

Black Bug Eye - 2.45 Arrival time please


I hope times suit every one

Sounds good

ME ME ME ME ME ME but probs late April so better get his skates on lol

btw, still havnt received your email bud

sounds intresting.

pm me a price andy

me to andy pm price cheers

Andy am in been emailing Andrew he's gonna do my Autronic

great stuff lads.

Welll for each option you need to add a switch,

Switch 1 - Anti Lag
Swith 2 Duel fuel

Etc etc

So i think we should all find some hight quality switches with lights on so we all know what option we are on, rather than fitting a simple toggle switch, a few relays etc and well be away!!!

Now the only issue that has come up so far is that the WRX will need the TGVS removed as the new software doesnt yet have the option to control this! BUT this is again been worked on.


Finn i have no issue posting prices on the forum so i shall when i hear back from andrew with more information but its may be £40/50 more than he charges us members of NESF already so we MAY be looking at sat £300 as always Andrews prices are very realistic


And the sale of a MAF on Ebay Snet etc should recoop you £40/50

would it be ok to have mine remapped normaly,

of course, the mapping of open source is still available the new mapping is just what some people want

Andy can you do a new thread for a mapping list to see what numbers we get throw me down as no 1

Is this possible on my ecu andy? Or do you need a 32bit?

Locky yes this is available on your car.... its NOT yet ready for the 32Bit cars


This will be like buying your self a Aftermarket ECU!!! but with out the expense P)

Just let you lot know, the 32bit ECU is fitted to the hawkeyes, the 16bit is fitted to the bug and Blobeye's.

Nice 1 andy......yeh looked back and your saying 32bit available soon duh! Cool will look out for the price ;0)

maplins sell the switches

Yeh I rember you saying last time marra.....I kinda miss read this the first time thinking I needed a 32bit.....maybe look to have this done with the next stage we doing andy ;0)......abit of a set back with work again!!! But I will get there

Whats the crack with measuring air temp then?

you normally need a air temperature sensor fitting, thats what I had to do on my mafless racerom.

this sounds good, will be interesting how long the 32 bit will take. As ecutek seemed to take an age

i must add this ISNT ECUTEK


Yes a Air Temp sensor will be fitted in the intercooler costing around £11

Im awaiting the deatails

Are you going to mention the lack of knock control on this ecu rom and the risks involved as a result ?

Fairly important issue and something I wouldnt want people to overlook in the rush for mafless on this experimental rom

Duncan,

Thanks for your thoughts on this BUT this has full knock control unlike the earlier group N Ecu Rom file, that i assume your refuring to, even tho the earyer group N Rom file also did control knock as a configuration adjustment to the ecu.

I cant go to much into tecy stuff but i know 100% that this new system HAS knock control and will work how any open source or ECUtek would

Andrew Carr wouldn't put any customers cars at risk, he has already mapped cars on this system and carried out various tests as have the designers of the new software set up

we any further forward with this being confimed yet?

heres what locky is running in his
