Hey peoples!

Just wondering if anyone else has experienced this...

2nd into 3rd while on full boost (mind you im only running 7psi) the car bogs down and then picks up and gets going again...feels as though something is holding me back? Its not wheel spin, Im changing gears smoothly too and not rushing the gear change...

This has happened since fititng FMIC, the front/dump pipe and new clutch (exedy heavy dudty) and just does not feel right, anyone have ideas?

Cheers,

Chris

how long is the piping run for the FMIC? how large is the core. sounds like you have introduced a much larger volume to the intake tract. so it take a bit longer to fill with boost, which give you less response.

agreed :D

just the small turbo not pushing much, when you say changing, is that like 4500rpm then a gear change? or 6000rpm+rpm?

If you get a bit more boost into it (10psi), and PowerFC/S-AFC to play around with timing etc etc.

It will fix that problem of a "hole" that your having.

sounds like your referring to a change gear and then the turbo is spooling but no immediate power, wait a second or three and then it kicks in again. Everyone notices that after they fit their first fmic kit. It eventually goes away cause you get used to it.

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.

      ok. Yea, then I would need to remove the turbo and weld an adapter on to it instead, if I fuc* this one up.

      Boost cut after swap(RB25DET NEO) R34

      No. Only for a standard ECU with/without Nistune. Standalone has no need for it. That's like the 3rd time I've said so.   And as to that sensor linked - yes, it does look like it would be the right one. I've never bothered to see how available they were - just assumed that they'd be hard to find. I think I'd be planning to go Link ECU rather than buy sensors I don't actually want to make Nistune work, if I did not already have Nistune. As you do not already have Nistune, you should realy consider your options.
