I thought that the link was pulling piles of timing because of knock?

Ole

today i sat the timing to 8 deg. slacked the wg as much i could without getting any slack and rattle.. now my pressure shows almost 3 psi. and my nb a/f meter stays stable at stoich at wot (about 2 leds from the green rich leds). however it glows when i pull over after draging through 1,2 and 3rd and if i stay wot up a hill in 4 or 5th with full boost.. I don't know what else to do.. :(

so one line under the 10° mark, correct.

if timing is good, then fuel is lean.

2 LED rich is like 13.8:1 AFR....you need more fuel.

Ole

so 2 leds from the green field is lean.. :( what can i do? do you think it will help to get some 1.8 injectors? what else do i need? I am thinkin of getting the aem wide band kit that they sell at flyinmiata for 305 USD.. is that any good? sorry for all the questions.. just total noob in miata boosting and i want to keep my pistons in one piece..

what are you doing for fuel? stock greddy kit with FMU? or that silly black box?

and yeah, I fi converted the numbers correctly based off a stock o2 sensor, the output on a 20 LED narrowband gauge should be something like that; .8v to .20v is 14.7:1, which as tyou can tell is nowhere near linear, which is why narrowband gauges are very hard to tune off.

Ole

I have the vortec.. not the black box..

Well something is wrong check the fuel pressure pull the plugs and inspect them. If you are truly at 8 btdc it should not glow significantly at 3 psi. Also you should make better than 3 psi as well you might also still have a leak that is blowing off with pressure kinda like a whoopy cushion this would over work your turbo and cause the glowing and low pressure. Did you clock the turbo i had compressor leak that acted like that.

Yes, lots of stuff:

too much psi
not enough fuel
small turbo
tons of knock

if anything you should be rich at wastegate pressures....maybe you hooked it up wrong?

Ole

I checked the vortec, and it's mounted right.. what do you mean by clock the turbo? how can i easily check for boost leak?

You can get the Innovate or AEM for less than $300 shipped on this board via a couple members. Wideopentuning sells them cheaper than FM and offers great service. I personally have the AEM, it works great and is very easy to install. I recommend it. You can find his information in member discount area of the For sale section.

I paid $175 for my LC-1.

Ole

But I also nead a gauge? I only have a Jacson Racing narrow band now.... :(

Braineack

iTrader: (62)

you can use that gauge. Since the LC-1 has programable outputs, instead of the gauge displaying results like above.

You can display your AFR like this:

Use the narrowband...you can just program the output for 0-1v

A digital gauge is only $7 (look at my site)...

FYI: I had glowing turbo and good A/F numbers, running 12.5 under boost and stoic in normal driving and turned out timing belt had slipped by 8-10 degrees retard!! Make sure your timing is happy and don't run stoic under boost :-) I also run the AEM UEGO wideband (a good wideband is critical not to mention cheaper than a new engine).

Ole

I just ordered 1.8 injectors from E-bay. Maybe that will do it?

bripab007

No, that likely won't fix your problem, although it might help mask it...you should be able to run 5-6 PSI with the stock 1.6L injectors.

You have a problem that needs to be diagnosed and fixed before you just start randomly throwing parts at it.

Braineack

BUT....having the 1.8L injectors isn't a bad idea. But like Brian said, you still need to find the cause.
