Pinging after Supercharger Install
Greetings all..
I am new to this forum.. Looks pretty cool so I'll have to stick around. Anyways.. I just installed a TRD 2nd gen Supercharger on my 2000 Taco 3.4L 4wd. Everything seems to be fine except for when I get after it from about 2200 rpms the engine pings pretty bad.. Now I have only had the Supercharger on for about 50 miles but I think that would be enough time for the computer to adjust... and I am running premium fuel. Any suggestions? Also, if anyone has pics of thier completed install (specifically vacuum lines & such) I would like to see them so I can compare my install..

GAWD! Great website.. but has anyone ever installed one of these superchargers and not had any problems? Is my luck really this bad? I mean this thing pings like mad no matter when I mash on it. So far.. thumbs down for TRD's supercharger kit!!!

check gadgets site as his site is very powerful for all SC owners.
maybe you're running lean, (not a SC expert) but you may need to retard your ignition and run it rich.
any forced induction system will have issues and pinging is a normal problem everyone experiences. if you've never installed one b4 you're in for one fun experience
also reset ecu by disconnecting the ecu fuse for a few minutes. easiest way is just to disconnect the battery and let it sit for awhile. As soon as the ECU is reset, it should reset everything.
just running 91/92 octane gas doesn't mean you'll be dumping more fuel, you gotta make adjustments.
can't help ya in detail as i've never done a SC install on any yota's b4.
sorry

You are suffering from the typical High Gear/Low RPM-Ping (HG/LR-Ping). We had to abriviate it because it gets talked about so much around here.
The problem is it seem that our engines do not use the knock sensors below 3000 RPM and it can not sense and respond to the boost induced spark knock below 3000 RPM. This is not a fueling isse, but an ignition timing issue.
We need to retard the ignition timing slightly between 1400 and 3000 RPM to supress the boost induced spark knock or HG/LR-Ping.
The two ways I have found to do this is with an ignition timing controller. The cheapest is the Split Second TMC1.1. This device retards the timing in that range a user selectable abount all the time whether you are in boost or not. It does supress the ping, but on your year truck it may set a check engine light miss fire code. This is because it only modifies the crank angle sensor signal and not the cam position sensor. When those two signals split to far the ECU for some reason interpets that as a miss fire.
The best solution for you is the Split Second FTC. This is a fuel and timing controller and you can just use the timing side at first until you want to upgrade your fuel system. This uses a MAP sensor to sense manifold pressure and it uses that and RPM on a map that you program so you can put in the exact amount of retard on when and where you need it and it does not affect off boost driving.
If you check back with me in a week I will have FTCs for sale at a discount. My new company is just getting cranked up and we are building our inventory stocks.

I do know that in 1999, there was a recall on the TRD superchargers for the Prerunner because of a "pinging" noise....you might want to take it to your local dealer and have them see if it applies to you. Then you can get it fixed for free.

(in smog test areas ie:CA) Would the retarding of the timing result in a failed smog test due to ignition timing out of specified range and /or high CO readings? With the use of the Split Second FTC, would this keep ignition timing in specs. at idle and keep CO within specs.? I have a 3rd Gen. and was planning on installing the TRD Super Charger, but if it causes the engine to ping, then it will never pass the smog for NOX. Also if I have to buy more components in addition to the SC, then TRD is not selling a complete or operational SC kit. Glad I cought this post before I bought one.

Mine pinged pretty bad to begin with, then adjusted and rarely pings now...it still does on occasion, but nothing I can't live with. I am also interested in that fuel/timing controller Gadget...please inform me when your company is up and running

Gadget,
Have you looked into this?
http://www.jandssafeguard.com/
"Using a single knock sensor, the system detects the onset of detonation and retards the timing on a per cylinder basis"
Individual cylinder timing control sounds like it would be perfect for us...I know some of the DSM and Stealth/VR4 guys that run this and it works great for them.
