Wow.... good to know that!! Waiting anxiously.................

Hi all,
Just wondering, for future development (if it hasn't happening), is there any possible we can integrate a function where we can tune a car via internet access? If this can be done, the tuner doesn't have to be in the car at all.. all they need is just a mobile broadband on the laptop which ...

Q1) Yes. Hot starting i mean is drove my car to grocery store, off the engine. After do some shopping, get back to car and start it to drive home after the hard starting procedure.

Q2) The Injectors LED always blinking when i trying to start the hot engine, which means the MS2 is catching the RPM ...

guys i am running 2.883 MS2 V3 and all these while its being running great except hot starting.
i have no problems at all during cold cranking and the engine fired up within the first few rotation but things really not working well during hot cranking. it always need long cranking until sometimes i ...

thanks a lot dude!!

yes i'm using SARD 1:1 boost reference fuel pressure regulator. its kinda hard to use the MLV to do the VE analysis as we need to load the Fuel VE everytime we done an analysis. another thing is during a road tune session, if we are in the Fuel VE map, we cannot see the AFR gauge update at behind ...

our MS2 fueling equation "PW = REQ_FUEL * VE * MAP * E + accel + Injector_open_time" is it possible for us to estimate the VE value at certain RPM/kPa?
here is an example. now at 5000RPM/200kpa, my VE is 80 in which i can obtain 12AFR. if i'm going to higher boost, let say 5000RPM/300kpa and to ...

i have a 4 cylinders toyota 3TC and it is port injections. currently i'm running 4 DSM 450cc/mins injectors in each runner. lets give a scenario that i have maxed out my fuel delivery with 85% of duty cycle.
if i plan to run another set of 450cc/mins identical injectors and make it 8 injectors setup ...

i've checked the wiring and i found out that the signal from distributor does not goes to the ignitor, it was fed directly to 4AGE ECU "Ne" pin. this meaning that the "Ne" signal is not a 12V square pulse as per MegaManual VAST instruction. Could it be?
the car runs fine with stock ECU that this ...

my MS2 previously was getting signal from a "ignitor conditioner" and i've bypass D1 and D2. now should i still keep the bypass of D1 and D2 and run a 1Kohm to D9 as per instruction?

I'm now currently building a Toyota with 4AGE 16V in it. previously the owner using stock ECU and runs a turbo in it.
I've made a connected between the stock harness to MS2 V3 board. I tried to crank it but no RPM signals was registered. I'm connecting the RPM thru the "NE" signal from the stock ...

how about the msq file? i just need to reload it back into MS2 with 2.8 code and it will works?

i've build my MS2 V3 board long while back. now i planned to upgrade the code to 2.88 for new added features. how can i know which code do i have?
and what are the steps to take for me to upgrade from 2.x to 2.88?

is it possible if fuel cut happens the engine will lean out and may be causing damages to the engine like detonation?

thanks for the info..cheers..

i've got a shielded ignition wire. the core will be connected to the negative of the coil(signal), how bout the shielded mesh around the core?
if refering the the wirings on MSII, Positive signal will go to Pin #24 and the negative will be going to Pin #7.
if i connect the shielded mesh to Pin #7 ...

if the total resistance (injector+resistor) is more than 10 ohms, i'll need to configure it according to the "high impedence" setup?

currently my wiring is 1 resistor (6 ohm) connected to 1 injector (2.9ohm), there are total of 4 injectors on my 3TC. refered to the VER 3 board external diagram, 2 ...

For low-impedance injectors (less than 3 Ohms), you need to limit the current to avoid overheating the injectors. To do this, there is a period of time that you apply full battery voltage [peak] current, then switch over to a lower current-averaged [hold] current, i.e. peak and hold. Alternatively ...

i've just purchased a MSII on Ver 3 board. i'm going to using 450cc low ohm injectors on my turbo Toyota 3TC. do i need to connect an resistor in series with the injector? if i eliminate it, do i need to make certain setting changes in the Megatune?
