Re: infineon 18 fets''houston wii have a problem'' (updated)

[lifepo4ever]

Hi everybody , i am sorry to start another post for my request but nobody answer my pm for the informationI need , I just read all the treads about 18 fet infineon controller by methods a lso and I found how I can mod the controller to 100 amp , my controller is stock from lyen .

I am not so skilled in to electronics, but know how to use a solder iron , for what I read the only thing I know is that i need to oversized the trace , and change for a 250 ohms shunt thats it but i need more information . my controller is already set to 100 volt but i only have maybe 40-50 amp of current on my CA so i just need to know what I have to do and where i can find a shunt to buy . with my old crystalyte mod by steveo i was able to do wheelie and i miss that feeling !!

I think the version of my board is diferent from methods tread .

 

[gwhy!]

the missing solder is not important where it is. The value of the shunt looks like it has already been lowered a little The solder what is already there could be beefed up a little ( use some solid copper wire to sink into the exsiting solder ). You would have to re-program the controller to up the current limit ( it would be a safer way rather than just lowering the value of the shunt ).

Hope this helps.

P.s Dont up the current to much in one go (up it a little and test to make sure the controller do not to hot )

100A on these things was always a bit optimistic IMO. There was alot of mods on that board so every change can matter. If you're already running 100V then it sounds like the regulator is already modded? Either way, you should be able to get up there. Definitely, program that bad boy and unlock the potential

 

[lifepo4ever]

ok so if I understand the shunt is for voltage ? not current? some i need to beef up the trace only?

 

[vanilla ice]

Shunt is for current!

 

[lifepo4ever]

so you see now i tought also it was for current also so i have to change value of the shunt

 

[gwhy!]

No, dont do anything to the shunt. Just re-program the controller for a higher current ( but as I have said do it in small steps and test controller temp ) and if you feel upto it beef up the traces a little.

 

[lifepo4ever]

yes I will try that , and order the usb cable from lyen

 

[grindz145]

Soldering the shunt is a way of tricking the controller into thinking it's pushing less current than it thinks it is. It's much better to reprogram, that way you're current limit settings are somewhat accurate.

 

[lifepo4ever]

i will reprogram it and see if it getting to hot i will give him more cooling or change case and build a other aluminium one with integrated fan with a switch so if i need to race i will open the fan

 

[lifepo4ever]

200amps peak will be great!! just for fews second i like chasing car but anyway i need a x5 to get 15 -20kw next spring

 

[John in CR]

What motor are you running? Low turn count motors will blow the controller if you try to run it at 100 amps, especially if significant hills are involved. Also, a shunt mod is required to get to 100A unless that's already been done for you by Lyen, because the programming doesn't go to a 100A limit so the stock shunt won't get you there.

4 stock shunts is plenty for 100amps. I'm running 4 shunts total in my 12 mosfet board and it was giving me around 90 amps without touching the programming. I would suggest in this case to just re-program the controller with the USB cable from lyen, and beef up the traces with some 12AWG copper house wire. You'll need the 116 parameter designer software, and the windows prolific driver. Make sure you have a 3/4 difference between the 2 current settings. Stock on the 12 fetter was 80/30.

Lyen is using a newer infineon board now, which eliminates the high ohm resistor, and big regulators. I think there is a diode in the circuit now and it helps step down the voltage before the regulators. Make sure you have a 330ohm resistor there, (I see the blue one in the picture) check it with a multimeter. Lyen said 330 ohms is good from 84V to 120V.

for now i wait for my cable so i don't know how thing work but with software it will be easy for me to change the value if some people tell me what to do
my motor is a 2807 and i think it can take this current no problem because my last controller was mod by steveo for about 90 amps and run since 7 month my motor still like new and there no trace of burn because i doubled my stock phase wire so i want the maximum what this motor can take .next spring i will buy a x5

if I mod the trace do i need to change the case?

 

[Doctorbass]

X5 is the TRUE life!!

Your avatar is far better.. but at that distance we can't be sure it's still not a travesti!!

 

[Ariane]

next spring I will buy an x5

:x Not X5 Rog is a bad idea is like to change something for something identical but with more weight (X5), keep your current motor you will be more happier and possibility for cooling on 9C are away better, it's my 2 cents and I don't like X5 and for the same price of single X5 you can get (2) 9C continent 2806 and build a killer 2WD. :lol:

Good day!

I think next year I will be doing the same. DoctorB, does the 5303 have 12AWG wire already so no modding?

And buy a 36 Mosfets controller if you bought a X5303. :wink:

Actually my 5303 is modded with 200 celsius AWG 10 silicone wire... and ... I kept and preciously used EVERY SINGLE STRANDS of each wire!

9c is very limited compare to x5 potential you never can get 20-25kw of power in a 9c that why want a x5 for now i have nice little set up but i am waiting to
made some more money to build more lipo nanotech and a x5 and believe me i will chalenge the car like doctorbass do !! i am ready to modified my controller at the bone also but i am not familiar with electronics i will have to send it to somebody i need at least 250amps peak

yes its a shemale you like it !! ok ok i will keep this little secret just me and you :lol: :lol: :lol:

10 AWG sounds good to me!
