Re: Adam's formerly supercharged... now soon-to-be-turbo'd, S14

Cool. I now have a spare 3655 with 4300kv motor with a 5mm shaft if you ever want to shoot for full vacuum :scared-eek:

Re: p00t's long winded journal from the beginning of time

I'm on the bigger Z32 aluminum brakes all around. Split point on the master for that car is ~350psi while I am at 500 (adds to the problem). So Z32 front and s14 rear brakes? If you get the Z32 rear you might not have to change your master but there still might be a tiny bit too much up front. Might...

I'm on a 10 mm spacer upfront to clear the strut. No rubbing on the strut so far with this setup. The tires are actually RS3... maybe V1s? But yeah they "communicate" well. Interesting how a track oriented car comes with silent tires... Might as well turn the music up! I would think you would need b...

Re: p00t's long winded journal from the beginning of time

Another track day at Waterford Hills in June. Only difference since last time was an oil restrictor added to the turbo to help with my sputtering issue which I think is oil related. There was an improvement so I am more confident I am after the right culprit. I ran the same oil as last time which is...

Re: Adam's formerly supercharged... now soon-to-be-turbo'd, S14

Most of the sensor circuits like the MAF on our cars has 100 kohm pull down or up which is good to use. Basically you want to pull the ADC line down enough so it is 0v reading. But you dont pull/push so strong that it changes the signal. So if you used 100 ohm for example your sensor might only be a...

Re: How to run LS1 Coils

The CAS disc isn't linked to the coils. Only to the stand alone. Specifically AEM's v1 and v2 standalone that everyone used. Basically the hardware isn't fast enough to keep up with the resolution of the standard CAS disc. So you need it regardless of what you are doing if you have an AEM. You can r...

Definitely worth letting it wind up to 7k by the looks of it.

You have the right CAS disk installed?

Might want to start a different thread about the issue you are having.

Either way you'll like the LS coils if you make the jump but get the issue straightened out first.

Re: How to run LS1 Coils

Depends on a few factors. If you are already running a standalone (megasquirt or AEM) then it's "only" the cost of coils, ignition wires, and wiring. I recommend just purchasing a full used set from a V8 that comes with the harness connectors and then you have spares (or sell the other 4). Cost for ...

I don't think you should have a problem with those "losing" the tune. Should be saved to an eeprom chip on both (good for something like 100 years and 10,000 flashes)

Re: KA24DE (NA) swap no start condition.

Glad you at least got it running. Having to turn the FPR down to 10 is aweful. There must be an input causing the ECU to drive the injectors that hard... Do you have consult or similar to see the live data? How are your voltages at the ecu, at the alternator, and at the battery? If your ecu is readi...

Re: KA24DE (NA) swap no start condition.

Sounds like you're heading in the right direction diagnosis-wise. If you unplug injectors and it can momentarily start on carb clean then your ignition is at least good enough to start. Sounds like you need to look at those injectors closer. Are they stock? Does your ecm have a custom tune? The only...

When I look at your tune in tuner pro I see the knock sensor box checked. I am not sure if Nistune handles that differently but it seems odd to me. Do you have another tune with the knock feature enabled or with the secondary maps in place?

What RPM does it happen? It happens at any RPM when apply throttle. Any load I apply at any RPM causes the AFR to go lean and then back to normal.

Also consider using an N60 maxima MAF. It will give you more stable AFR versus the G70 one and it is less restrictive.
