Excellent job

I truly appreciate your share of knowledge and time spent to make these very helpful videos. Thanks

I realy appreciate this informative explaination..thanks alot thanks alot🙏

Fantastic explanation really clear and easy to understand. Thank you.

thanks! great video. very clear reinforcing of the basics.

Aek namber bro❤❤

Nice presentation good information thank you sir

First time I see practical sensor ntc and switch input how it changes in the ECU voltage.really very informative class. Thank you sir🙏

Thank you for that,much appreciate

Great job .

BTW.. If you did accidentally write on something with permanent marker-- you can just scribble over that with the dry erase marker, and it will magically erase the permanent marker when you wipe it as normal. Works really well. I think they are just mixing some type of acetone or alcohol or whatever in the dry erase marker, which is otherwise just the same as a permanent marker. (if you took out the solvent).

in two wire EGT(Exhaust gas temprature) sensor, is it possible that if exhaust gas temp. remain high for long time which leads to low resistance on sensor and that makes high voltage input to ecu for long time and it make ecu circuit to damage? can i have your email or other contact to discuss this query?

Hello sir I hoppe for some help. I have old Opel Ascona C 1.3l 85 model year . It has the classic GM staff on it . I tryed multipel atempts to some how retard ignition timing. I use the E core 4 pin design ignition coil,pick up coil and the 4 pin GM ignition module. My land does not have that special 5 pin GM ignition module and its to much expensive to order it. So what can I do to those circuets to manuali switch that circuet to deseired fiering engine degree with out turning phisicali the distributor? I did try out dual ignition modules on 1 pick up coil it did fire bouth seperatli ignition coils so I wondered if I culd simpli use dual ignition modules in 1 ignition coil just change resistor values or sone thing remote controled. Ya know Im confused lot some peopel say use schmit trigger some say use variabel ignition system but my car is to old it does not have crank sensor or other staff ever if it did have it to old car cant finde correct plugs with wire resistance . I did kinde of used speaker wire and 500k potenciometer from + pick up to + input signal to module it did kinde of worked but not how I wanted engine run terribel it seams only I restrict current or voltage going to ignition coil not reali retarding and insted fiering on compresion I ended up fiering at exaust stroke insted more or less engine run but crapy and did actuali run fiering at exaust stroke after long cranking. So any sugestion please? I did as well tryed out that plasma ignition staff was nice tought but caused havoc on my delco 12si alternator starting current didnt go as planed how I wanted it those were ceramic hv capacitors. I did notice the 4 pin gm ignition module does not have zener clamping diode in its circuet I observed the mc 3334 ic chip design on google and found out my car does not have that zener diode so aperantli it can cause miss fire or do funy staff if static is present on the chassys or arcing. So I dono what to do ?? I did figure out maybe I culd use external circuet after all the ignition module needs only + from the pick up coil not the - to work so I tough perhaps some disruptor circuet atached to the - pick up wire migh some how disrupt the signal for a while. Any way I need any circuet that can retard ignition timing on my existing ignition system. I dont have any upgrade posibilitis. Im not shure if capacitor/resistor box might help or not Im preaty much confused how it is done voltage/frequency regulation is done basicali on a 1 wire ac generator . At this stage Im desperate .
