The only goddamn bloody difference between electronic and mechanical gauges, is that in an electronic gauge, the electronic sensor converts the signal from an analog signal to a digital signal, which can then be carried via wires through the firewall up to an electronic unit which converts it back to analog. In a mechanical system, the gauge simply reads whatever pressure level is fed to it.

Imagine having a mechanical oil temp gauge - > and the oil line inside the cabin breaks and you get 80 degree oil poured into your cabin ;)

Electronic Gagues are more accurate and more expensive

Mechanical arent as accurate and are cheaper.

plus depending on the gauge can be dangerous.

if you have the money always go electronic.

Digita signal??? Doesnt it just convert the reading into an analog signal; and then at the control unit reads the signal where a certain voltage equals whatever. I dont think there is a need to convert anything to digital

Most gauges in domestic cars should be electric, therefore reducing the risk of exposure to unwanted stuff like hot oil...

Most performance cars in the states and drag racing use mechanical, with such items as fuel mounted externally under ANDRA regs etc.

The best responsive gauges I have found are mechancial especially with regard to boost. I have always run mechancial in other cars but external mounted, otherwise run full sweep electric (I like Autometre sorry).

Most Jap ones are electric for the reason that they install them inside the ****pit!!!

Is there a reason why you think the mech boost gauges are more accurate. An electric gauge would be able to put the sensor within a few inches of the preessure source meaning that it will react very quickly, whilst the mechanical gauge needs metres of hosing so it can be plumbed up to the gauge....plus surely a diaphragm and voltage signal will be better calibrated/more robust then a mechanical gauge????

Who needs boost gauges anyway..what you dont know cant hurt you:)

mechanical boost is more accruate and responsive as despite the tube being at a distance, the line has a constant pressure. Whereas the electronic measures at intervals and then transmits the data from the sensor to the guage itself. Some electronic ones are good, however I cannot justify $300-$400 for an electronic boost gauge compared to a mechanical when it does the same job. For other uses I would go electronic, such as oil pressure (sometimes it can be beneficial for a mechanical as well in some applications), water temp, oil temp as these do not move in a huge hurry...

    • Brooooo Please send ABS control unit schematic Please! R33 gts25t ABS (Its two plug ecu, black and white) wire colors possible? [email protected]
    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
