I have reflown around tle8888 but no improvement, still nothing and 0.00A power consumption. I guess chip replacement is the next step.
You have hot air and flux? Do you have solderbraid also?

Re: microRusEfi

I think that may be related to a halfway working power supply.

I have cranked until starter cant turn the engine, but never had a shutdown

Re: microRusEfi

Add a lot of solderpaste over the pins, and pull your iron over(laid flat)


You only need 12V at pin: 54, 87 and 90

And key at pin 49

Then it should be running

Do you have another 8888 to try?

Now, with vision you are able to solder it.

Re: microRusEfi

Yeah, looks good but I always check anyway.

I usually use a knife like this, scrape careful between pins, and twist to make sure pins are soldered.

I find this really strange.. I dont see how you can have killed a 8888. I have tried a lot, but never made it :-)

Re: microRusEfi

Ok, sorry. Been driving all day and just got home.

R20 and R5, both ends of them

If you have voltage at R5, and all soldering are ok, you probably have the first 8888 that power supply fails.

I have beaten them so bad in every way, and never damaged any. So I really doubt it.

Re: electronic throttle body control ETB

You need to connect Dir1 and dir2 to MCU.

Select pins in TS, and use the settings in menu

Set Dis pin Low with resistor, En pin high with resistor.


You can find my schematic for it in microrusefi folder

Re: launch control

The most "important" part are to generate boost.

If you can implement ALS as well would be great.

Now with E-Throttle we dont need bypass-solenoid anymore.

Re: rusEfi own wide band controller board add-on using CJ125

Are there any gauge in TS to show AFR from CJ125, or how do you do that?

I have a CJ125 up and running, but no way to show it at a gauge.

Btw, I spotted this today while making a tuningfile for a Ford Focus.
It has a lot of CJ125 settings.
