I was just reading the FSM and it says to adjust the screw so that you have 800+-50 RPM idling at operating temp. Problem is the ECM is outputting a predetermined duty-cycle for those conditions.
Since you are specifying your own duty cycles with the AEM, the screw's position is not as important. I would suggest you set the screw somewhere in the middle and tune from there. I can only see you needing to needing to adjust the screw if you need more airflow during a cold start. For example, my tune uses 100% duty cold and about 75% warm. So if your crank timing and starting injector pulse width are correct with the idle motor at 100% duty and it still doesn't start, increase the airflow via the screw. I am using Haltech, so some of these terms may be different, but it should be the same idea for AEM. |

yes, im well aware of that. BOTH must be set to proper voltage for proper idle tuning. the plastic screw (later metal on the notchtops and blacktops) sets a control voltage in the IACV. the throttle set screw sets TPS voltage and sets the correct opening in the throttle body for the car to idle as well (as the throttle body is never fully closed on the SR)... its a 2 part system, both parts need to have proper voltage for stand alones AND OE ECUs to function and tune right at idle. you can mess with the IACV screw once BOTH are properly set to increase or decrease idle speeds (proper idle speed on an SR is 750-800 normal area for deviation). however, if you have to major increase or decrease the IACV screw, you have a vacuum/boost leak somewhere else in the motor (or at the intake manifold). its a pain to set both perfectly, but once you get it, the car idles flawlessly. took me about an hour of dicking around with both to properly set them using NISTune/Consult Cable, but Ive NEVER had idle issues since... and if i do, i know something is leaking or off somewhere else in the motor.

Is there a way to know what model, base or se, S14 you have by decoding the vin? I thought that getting the car fax would have listed it, but it doesn't and this car confuses me.
It is a 4 lug, but has abs and a sun roof. When shopping around on amazon, the base model rotor option for the base model is only non-abs. I am not going strictly from an amazon selection, but I just want to know for sure what I'm driving.

It's a 1995 and I don't think it's from Canada because it wasn't listed in the Carfax and it doesn't have KM/H on the cluster.
BUT, come to think of it, the cluster might have been changed because it reads less than the carfax report(facepalm). Thanks for that site. It seems all of my answers are in the Model Identification Number.

I lost the screws to the lower steering column trim when changing out the ignition switch, does anyone have the size of the screw that would be a good replacement?

Looking to buy some wheel spacers for my car and have a few questions, any help is appreciated.
I want to get 20MM up front and 25MM rears. 1. What brand would you recommend between Ichiba, Circuit Sports or Blox (if there is a better brand please post it up). 2. Anyone used Loctite Red for the installation? 3. I see a lot of people using sand paper for obvious reasons, I'm wondering what grit is best since nobody seems to post what grit they're using. Thanks in advanced.

I spent a little extra to get Ichiba and really liked them. I didn't know Blox made spacers at the time, but now that I've looked at them they seem pretty good too. They even have some (except Nissan unfortunately) made from AL7075, which is the best available. That says something right there.
I wouldn't use Loctite. The torquing is more important. I used to work a tire shop that had a re-torquing policy and I've followed that ever since I learned about it. The idea is to re-torque the lug nuts after ~40km. You'd be surprised to see how much they back-off in that distance. Using Spacers makes the whole process a bit more challenging. It would go like this: 1. Install spacers and torque them 2. Install wheels and torque them 3. Drive ~40km, remove wheels and re-torque spacers 4. Re-install wheels and torque them 5. Drive another ~40 km and re-torque wheels After this process, you're pretty much guaranteed no future problems. Just be sure to torque the spacers to the lower end of the range to prevent the studs from spinning in the aluminum spacer (which is softer than the steel hub). As for sand-paper. You need to understand grit. The lower the number the more coarse the paper. Coarse paper is for removing a lot of material but will leave a rough surface finish. Higher grit will not remove as much material but will provide a smoother finish. You can always work your way up from coarse to fine. Just keep in mind that you are removing material if a precise fit is required. I'd say a good all-purpose grit is either 120 or 200. |

Stay away from Circuit Sports spacers. They work, but their spacer lug nuts FAIL. Their Lug studs FAIL. Get Ichiba or HHR or anything BUT Circuit Sports No loctite. Torque the spacer lug nuts and your wheel lug nuts right and don't look back. Check spacer lugs every 3500 miles when you change your oil and rotate your wheels

Also I believe the intake/intercooler piping is different for the s13 and s14 SRs but I would like to know if it's because of the engine or the chassis because I have a notchtop SR into an S13 and I'm wondering which one I should pick if I want a new intake/intercooler piping kit. |

can always buy the s13 one and make it work or vice versa. Kinda like when you swap to t28 on an s13 sr, play with the outlets. At least that's what I would say according to my research I'm sure a google search will produce the result desired, or someone can chime in |

That inlet runs to a catch can, other side of catch can runs to the front of the valve cover T.
Also run the stock oil/separator if you can and/or s13.4 valve cover for the best solution. |

-Is there any special consideration that needs to be made to mate a s13 KA24DE to an s14 5 speed transmission? Looks like the only thing I can find is to just leave the CAS installed/unplugged. Is that it?

Anyone got to try these gauges?
http://zilvia.net/f/showthread.php?t=452448 The seem to fit my needs perfectly. The only thing that bothers me is the 1/8 PT fittings for the sensors (a opposed to NPT). Can they be made to fit the Circuit Sports relocation kit? |

Diagnosing a no start problem for my S14. Dash lights and all accessory works as well as power mirrors and windows, but car doesn't start. Starter makes no noise at all or click. Fuel pump primes and pressure is fine. I checked all relays in the driver fusebox they all work fine, same thing for the Clutch ASCD or whatever in the bay which the relay works as well. Starter was checked at Autozone and they said it works fine. Checked power at the starter said it was getting constant 12 volts when probed. Chassis grounds are fine as well. The only things not checked was the ignition switch or spark. Spark should be fine though had new plugs in a few months ago. Just need to check dizzy and ignition switch, but anything else that would cause my car to not start? It randomly just did not start when I turned it off after driving it for like 30 minutes.
