R34 Questions! (Turbo, E85, Mounts Etc)

[Bratva]

Hi

Just would like some tips on a few stuff.

1) Say i have buy ethanol content sensor, would it be possible to get a tune done for a nistune so i have 98 tune, e70, e75 and e80 maps loaded on, then when i fill up, i can check the ethanol content on the reader and then plug a laptop in and load the correct map via the consult cable ? How much would this involve in dollars usually, i would assume that would be considered four seperate tunes.

2) If i purchase a wideband sensor + gauge + controller say from innovatemotorsport, would i be able to replace the wideband with my narrowband ? Would the controller be able to be plugged into the stock wiring for narrowband, and then be able to use the wideband for tuning, or do i weld in both sensors ? and would it be compatible with nistune, or do you monitor that seperately?

3) Would it be worth upgrading engine mounts when going from stock to 300rwkw+ especially that the intake manifold and turbo are both out, is the job not too hard for the side mounts ? Any diagrams or guides ? I assume you just take out top and bottom bolt(s) then jack up the engine a bit and pull it out ?

Thanks

If your going to that effort get a flex capable ecu and do a proper flex tune, so simple and less risk of any issues....

As for engine mounts, unless they are worn or

Broken then leave them as is...

you will spend more tuning multiple tunes on the nistune than you will getting a flex capable ecu and having that tuned properly

[Bratva]

If its slightly clunky when shifting is that reason to change the mount(s) ?

What would be good ECU for flex that you would recommend ? With AFM or with MAP ?

[34GeeTeeTee]

There are a few options out now and so far they all seem pretty successful.... They are generally MAP.... Mines not P&P so not the best option

As for the clunky, I wouldn't know without hearing or feeling it, it's possible but more likely driveline related?

yeah, i wouldn't bother around with all that if you're running Nistune, get an ECU with a digital input.

You'll find most people run the Link G4's for this sort of thing, or the Vipec equivalent. There is a plug'n'play for the 34's.
