Exclamation -- Updates, ReRace! Movies -- Vishnu V3.1 vs JB3

Here it is again...
This is two happy races between good friends.

Both cars are modded with DP´s, IC, exhaust and DCI.
Pump gas in both cars.

The camera car (mine) is tuned with Vishnu V3.1 stage 3 map 5-29 with default UT (85%) and my friends car is tuned with JB3 map 7.

Both cars are very strong, but it seems that the Vishnu-car was a little more stronger this time.

Please dont start a tuner war now!

50-260 km/h (And for those who might wonder: Yes, we start at the same time. I have a really good torque on 2nd gear in 50 km/h, which explains the jump in the beginning.):


100-260 km/h:

Nice vids and must have been fun! FYI - The 5-29 maps are considered a V3.3 map. I am assuming you were using the Rev I procede hardware (non-canbus)? I personally think the 5-29 maps are much stronger than the last 2 shiv has released. I may even drop back to them.

In terms of warm engine performance, the 5-29 maps are identical to the newer maps. The only difference is that the new maps limit/reduce boost when the engine is cold or excessively hot. We haven't changed anything in terms of boost target, timing curves, compensations, fuel mapping in months. That will change shortly though

Big Tom-- good runs!

Cool. Then it is in my head, and I just got used to speed.

Big Tom - Can you specify what companies made each of the bolt on modifications on each car?

Could you remind at what temperature boost is reduced? 260F?

Nice vids - looks like the Procede car got a bit of a jump in the first vid and put some quick distance on the JB3 car - second video looks like a better start, but the Procede car definitely is on a slow pull away!

It slowly starts to reduce above 258f. We also richen up AFRs. Pretty much everything we can do to aid in engine cooling without inducing a sudden obvious boost cut situation.

WOW this is the first video of two identically modded car with different tunes run side by side! In these videos the Procede looks like its a bit stronger.....Not saying which is stronger and start a war, but just stating the facts of what was shown....
