Hello:
I am of Spain, I have a Evo Viii GSR, with cams Brian to crower 272/272, to air intake ARC, line of escape Tsudo N1 3" , test pipe Megan-racing, am going to install roms of ralliart edm, I need to modify some square of the ROM? , I have understood that the roms ralliart come very poor in the mixture. It is necessary that it buys wideband LC-1?

Best regards.

Michael.

P/D: Sorry, my english is very poor.

 

Michael,

The LC-1 is a good tool for anyone tuning and really should be part of your kit when working with the ROM on the car. As far as modifying the ROM to make the ralliart work, we havent had any ralliart editions here in the US. Perhaps someone in Britain can chime in and help?

 

Thank you for responding so quickly.

I already have the rom Ralliart EDM, and I will burn with ecuflash and cable tactrix. I am afraid that the mixture is very poor and break the engine.

 

Post your rom and use EvoScan to log TPS, RPM, O2 (front), Timing, knock, coolant temp and octane. Do some full throttle runs and post the log files here. That will give us a LOT of info on your setup.

 

Thank you very much for your help.
For the value of o2, do I need the LC-1?.
I will realize tests with the evoscan and will send them to the forum.

Very thanks

Michael .

 

michael,

Just using the NB voltage is a close guess in lieu of the LC1, but the WB is the sure bet.

 

Ralliart maps tend to be a little lean in the midrange, especially if the boost is above standard. The cams will probably make this even worse, so just be careful without an WB.
