the M35 VQ25 is listed on the SAFC Neo and and SAFC II installation lists. but not the SAFC 1, which is probably not supported because the SAFC 1 would have been designed before the VQ25 was in production.

i don't see why you couldn't get it working, its just a signal bender. what were the reasons behind not having any luck using them?

im running SAFC II works well for the limited tunability it gives. Still waiting for someone to flash the factory ECU's

Bump!

Has anyone else since tried the SAFC/AFC Neo options with their M35 stageas?

@danwatt

Can you give us some more info on the results you've had with the SAFC II?

Thanks

I'd be interested in this too. I had great results from a SAFC2 on my series 2 stagea. For the price its a bargain (2nd hand FTW), especially if the car is otherwise standard or only lightly modded.

I'm sure I read on here that the M35 ecu somehow counteracts the effects of the SAFC or something along those lines...anyone?

the problem with any piggyback computer is the ECU on the M35 is self learning.

So when you make changes the ECU tries to compensate for changes made to the input signal. Not a waste of time just very difficult.

usually the side effect of the SAFC was that it advanced the timing. But it was still good enough to get the AFR graph to flatten out once it hit 12:1 and stay at 12:1 all the way to redline. This was on a 99 model with full 3" exhaust and GT30 turbo, and with the base timing advanced a little also, the fuel economy dropped by 2L/100km. It was a huge improvement, mainly in the mid-range.

I guess the problem is that the ecu has so many inputs it uses, and with the SAFC you're only changing one of those...

      Duncan's V37.......race car?

      By Duncan · Posted

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
