Would I Need A Tune Asap If I Were To Install Headers And Hfc's?

[xj265]

Hey Guys

I just wanted to get some opinions please:

I just got some headers and HFC's and from what I've read, installing both of them would mean my V35 would be running very lean? ( My mods so far are: drop in K&N filter, Z Tube, TDX2 exhaust)

So I was planning on waiting to save up some more pennies, get the headers and HFC's installed then get it tuned ASAP at east coast customs in Brissy with the UP Rev software, so I may not damage the engine.

Am I being a bit too over the top about having to get a tune straight away? My V35 is my DD so it gets driven very often.

I would say doing an ECU reset would be enough to sort out any leaning issues. Its not like your slapping a super/turbo charger on the car thats going to boosting a significant amount of extra air through the engine requiring a significant amount of extra fuel to be added to the mixture

No, just reset the ecu. Unless your goin cams or injectors or something like that the factory computer can keep up with it

That said, you'll get the best benefit out of those mods with a tune

I wish my cars tune was done :S the ECU is over in Texas atm!

Wtf?

Why is it in Texas? Did they brick it?

[xj265]

hmmm interesting, thanks for your reply guys. Looks like I may just get them installed without a tune then just a reset

What else gets reset with a 'ECU reset' though?

I believe Glen's ECU is in Texas because

Thats complicated! First run was 166rwkw without a tune.

My ECU didn't seem to like Uprev; it had a Master rom version they hadn't seen before so its with Uprev to get it sorted.

Only thing that gets reset is the learned fuel settings. And the dtc codes.

I would be asking serious questions why ecu is in Texas. I have been down the new map path twice with uprev, both completed successfully without the ecu leaving the car. Was my car, pnm35 and a adm pathfinder.

My bet is that they tried to flash a file onto the car from a different ecu and bricked it. Now they are trying to recover it. Hope your not paying for it.

Yep PN-Mad you got it in one. They have been really good about it trying to source another ECU (difficult because its a manual), and got it sent off to Uprev ASAP.

They are sorting it out at no extra charge to me, so I'll let you guys know how it goes. I've been happy so far with the way they have dealt with it; by being upfront and honest about it and trying to do what they can.

Luckily I've got a motorbike as well!

[PN-Mad]

Good to knowthey are sorting it out. Hope it works out for you quickly and effectively.

Frustrating when they just had to take 2.5 hrs to dump the rom, send it off to uprev, and in about 3-5 days you'd have it back cracked and coded.
