Be thorough and methodical with your testing so there are no ambiguous results. But, the most important thing is to be SAFE with your real world tests! It will be exciting to find the limits of the tune, but things happen so fast at 180+ mph!! I'm sure you have good places to find the upper limits, but wildlife at high speed can be just as deadly as a car. Be careful, and maybe it will take more than a day or two to find those limits, ease into it.

Boots, if you guys go for a dyno day, please let me know. I'd be interested in getting a baseline. Thanks!

Hi Guys, anyone know is there any difference between the two ECUs? As of the driver side n the other passenger side cos I mix them up during removing them. Thanks.

Very important you work out which is which. I was specifically asked to mark my ECUs drivers side and passengers side for the remap. Would contact BR Performance and ask.

man.... no answer from boots.... did he get caught speeding...? hopefully not...hahahaha

6spdterror · 03-04-2015, 01:30 PM

I hope boots isnt in jail!

boots · 03-04-2015, 02:36 PM

Lol. Naw not at all. I have been so busy at work prep our equipment so I can leave for offshore next week. Besides we had a few days of rain. I will get you guys some info as soon as I get a break. I'm anxious also.

Great to hear that u r alright cos I'm also worry about u. Lol

BR didn't programme it with the bigger turbo that I have cos for custom they need the car to be there on the dyno so instead I got the stage 2. Can't wait to get it bk n put it on the dyno to see what's the gain difference with the piggyback.

YOu will still run out of fuel and run too lean with more airflow. You should put oem turbos back on.

boots · 03-04-2015, 09:28 PM

I'm doing good Andy. Thanks for looking out you guys.

When I was on bms with bigger turbo, no matter how I turn up the boost the car just can't run better n it was infect slower bcos the turbo spool much later.

I'm always running very very rich till 10.6 AFR at high rpm with or without methanol.

So with bigger turbo is not running lean but is more on the car isn't really response to the piggyback with the upgrade turbo.

I will try again this time on the dyno n my Qstar on timing n power.

Boots, test out the car n let us know your results.....

Maybe the part numbers on the ECUs can help you work out which DME goes on the Drivers and Passengers side?

With more air from the turbo you need more fuel in order not to run lean. How do you know you were running rich? Do you have a wideband?
The turbos from Vargas only upgrade couple small things; the A/R housing and inlet are still the same. The spool time would not be affected.

Yup I hv a wideband sensor, These are the spec I got from them :
Compressor is 52mm inducer x 68mm exducer. Turbine is 50mm inducer X 44mm Exducer 12 degree clip.
I had tried with my Gstar timing gauge n the timing drop 0.7sec on a 100-200kmh test. Sometimes is slower by even more than 1sec, the turbo spool much much slower at almost 4000rpm. This is from my true experience, if u ask me why I also wish to know the answer.
The whole Arka exhaust system sounds so different after the turbo was installed, it doesn't sound as solid as before anymore, very difficult to tell u why unless u experience it yrself.

Andym3100k · 03-06-2015, 08:33 AM

Just got my ECU back n hook it up.....
For sure the car run much more power compare to my piggyback. I will arrange for a dyno next week to see the actual gain over the piggyback.
Overall this is how I feel.
BR stage 2.
AFR at 12.5 to 11.6 when turbo kick in at about 2600rpm to redline.
The turbo spool much faster at lower rpm
The car will swing to one side once you full throttle & the DSC light keep coming up. 2nd & 3rd gear.
I think the redline is been push up.

Piggyback
AFR at 14.5 to 10.8 when turbo kick in at about 3000rpm but will only turn Rich after 4500rpm & reaching 10.8 after 6000rpm.
Turbo will only spool after 2800rpm.
The car will only see DSC light up in a quick brink form in 2nd & 3rd gear.

Can't test the timing bcos of road condition but will try to do it tomo night again. Overall I'm happy about it.
