I fill my car up at my local United. Give it a blast in 3rd gear, if AFRs are between 11.2 and 11.8 keep thrashing.

I reckon that if tuners like reliable engines the only way you'll ever get a good flex tune is blending low octane ULP with ethanol . Hard to imagine Caltex and United using 98 PULP in their E70/E85 p

Hey all,

Just wanted to ask a quick one about fuel filters. What are you guys using these days? I've read a number of older posts about using the standard Ryco filters, some good some bad. I'm also aware of the situation with needing to replace fuel filters regularly just after switching to E85 until the system is clean. So right now I'm considering three paths.

1. I stick with the Ryco paper filter and just replace it regularly.

2. I stick with the Ryco paper filter for now, then after my first tank of E85, switch to a billet filter (Aeroflow, Speedflow, Proflow, or similar?)

3. I switch to a billet filter now, before getting the E85 tune.

At the moment I'm leaning towards option 3 for a couple of reasons. Firstly I have the standard feed line to my Ryco filter, then a -6 fuel line to my HKS rail. It works, but considering the Ryco filter has 5/16 push on barbs, it doesn't quite fit as nicely as I would like. With the billet filter I could use a -6 AN fitting on one side, and a -6 AN to 5/16 tail barb on the other side. Second, if I need to replace filters regularly, would a washable element not be a cost effective solution?

I use twin -6 an stainless mesh filters, Proflow ones, they cost around $100 each though plus fittings. No issues in 3 years daily driving on United mainly, and they have never been cleaned.

Do you know what micron filter element you've got, Scott?

Another one, where are people mounting their GM flex-fuel sensors? I've got the flow through type and I thought I could mount it between my regulator and return line in the engine bay, but I can't see it happening. This thing is quite hard to mount with the factory hard lines :glare:

In the boot. Tee off the return line just before it drops back into the tank. Hidden sensor FTW!

Yeh? I did think of putting it there. Could maybe work something out... All seems a bit tight though, I can hardly see my return line let alone find a place to put two tees into it :/

BRB, taking a photo for you :P

I think it's 100 micron mesh.

Don't you want the sensor as close to the rail as possible?

I can't see how it makes any difference. Either way, once the fuel is mixed, it's the same. Just dontn belt it until you see the reading settle.

Ah, you got the little small thing.

Yeh so they say. Its fkn massive! Ideally I would mount it close to the rail, but I can't see it fitting anywhere unless I remote mount the sensor and run like 2 meters of hose to it :/

Just curious why I've seen a few setups with the flex sensor mounted in the boot? Another car I've seen setup by UNIGROUP has the flex sensor in the boot too?

What are the benefits? Is it just a convenience thing or heat stress thing?

It's one less thing in an already full engine bay. No other reason.

How many free 0-5V inputs do you need on your ecu? The zeitronix Eca kit outputs fuel temp and ethanol % doesn't it?

1 I'm pretty sure. And yes fuel temp too. You can set up fuel temp correction too

Yeh this is what I was thinking of. It would be so much easier if I could cut the standard hard line, but I don't want to lose the flared end.

I think the easiest thing would just be to run a longer length of hose to the sensor. Just seems such a messy way of doing it :/

      Yet another RB Neo misfiring thread after reading all the others.

      By uchoa · Posted

      Hey folks. I've been lurking and browsing the forum for a while, since I got into my head that I wanted a skyline. Having purchased an overpriced completely stock GTT, (only "mods" it has is HKS pod filter and catback) now that it became legal in the US, it was all glorious and sututu noises here and there. But then I wanted to do things right and went to do basic maintenance. After all the fluids, filters done, I did the spark plugs, that's when the problems started.. First the car started spluttering at around 4.5k RPM. Which I gapped down the new plugs and that solved the sputter there, but the car now always misfires at idle with pops when lifting off and shifting 2nd to 3rd. Similar to the issues in this recent thread. I've been banging my head against the wall, reading the threads here and trying suggestions for a couple months now, so decided to start this one to explain exactly what I tried and what is going on. The symptoms of the issue: Idle and low revs misfiring intermittently. You can hear the exhaust tone change and the shakes on the shifter knob. It happens frequently, but doesn't seem to have a rhythm to it. Pops when backing off throttle. It pops and or burbles almost feels like it spits fire when it pops. (Happens mostly in 3rd gear at around 2k RPM). When under load and after 6k RPM, it also pops when shifting from 2nd to 3rd. There's a ticking noise at around 2k RPM in 2nd gear going downhill, seems unrelated though but I am out of educated and downright dumb guesses. Not noticeable lack of power when putting the car into load. The attempted diagnosis and solutions: Unplugging coils when the car is running This did nothing to change the idling and tone shift for every cylinder. Checking the exhaust headers with thermometer They all are within what I'd say it is margin of error of the laser thermometer New spark plugs Tossed two new sets, copper, iridium and using the old ones, still misfiring, even re gapped to 0.8mm, still same thing. MAF cleaned with the "specific" spray cleaner No changes in the issues what so ever. Brand new loom and r35 coil conversion (was going to add the r35 coils anyway) car runs arguably better, still misfires, but seems like does less frequently. Placebo? Code 21 now being thrown, thanks nissan gods. Removed the CAS to check the shaft for play or anything. CAS seems all fine, nothing that indicates any issue, visually speaking. Things to attempted next: Ordered a new MAF (chinesium from Amazon, to be able to return regardless of result). Fuel with proper gas, maybe it is this California water that they sell as gas that is to blame? Plugin the link ECU and check the info using the built in base map. Go back to BMW and eat my rob bearing breakfast without milky oil mixture.   Do any of you have experienced anything like this or have any suggestion?

      Hello! I had a mid life crisis on a budget and coincided with the R34s being legal in the USA. And now I am here, with it having old car problems and me slowly hoarding parts to start building it to what I envision. Essentially I made a mistake, that lead me to join this forum filled with legends.
