RomRaider

Hey just wondering if anyone has a map i could use for the parts im putting in. i have a walbro fuel pump, Ultimate Racing 785cc injectors, up and down pipe, stock intake, HKS Bov, and a manual boost controller. i may take out the manual boost controller if i cant find a map for this. i just need something close to these mods so i can have a base and ill adjust it later on thanks

MBCs are generally a bad idea, but were nice to have back in the day when there was no way to change the boost and wastegate targets directly in the ECU. If you are using RomRaider, then you now have that capability. If you have one the classic MBCs that operates all the time, then your ECU has no control over boost whatsoever. This is why you can run into problems with part-throttle full boost. Other MBCs only operate at full throttle, so your FBC deals with your part-throttle boost. Regardless, I would ditch it as it is not necessary and cause problems.

Ya thats what i was thinking i should just get rid of it cause i dont want to over boost. is it possible to get a map anywhere for the set up needed without the mbc.

ev8siv3 has some stage 2 maps available at osecuroms.org. You'll have to rescale for your injectors as these maps are designed for the stock injectors.

so to tune for my injectors all i would have to do is go into injector flow scaling and change that to 785?

that sounds about right, although you should also check the actual afrs afterwards. Changing this value will change the amount of fuel the ecu puts in during open loop. Increasing the value will mean that the injectors are open for less time than before, so less fuel is put in, and afr will be leaner.

I've seen this table allegedly from Christian@cobb on the injector scaling issue. Pretty sure that punching 785 won't work.

now is this in addition to scaling the injectors? i plan to mod my injectors pretty soon because my idc's are stupid high.

Yes, sorry, you have to put enter these values in the Injector Opening Time Compensation table as well as updating the Injector Flow Scaling table with the new injector size.

wondering if anyone has made a map for this yet?
