Thank you for the tip! That got me pointed in the right direction. I realized that since the light flashed in wasted spark mode, I could set the base timing there. Sure enough, once I correctly configured base timing and switched back to DSI, the engine fired right up. Here’s my trigger/sync...

I'm running stock-style TRQ ICA65565 coils, and though I haven't found a specific dwell table from TRQ, I think my table is pretty accurate: actual dwell in wasted spark and DSI modes are comparable, within 0.5ms of each other.

I have been having some issues trying to get my freshly built 2005 4Runner 2UZ VVTi with Link ECU piggyback running. It has run recently: it idled well; and I could slowly raise the rpms, but if I gave it any real throttle it would cut out. I’ve made a number of adjustments to try and get it...

Thank you! Okay, we got a fuel pressure gauge on it, and it's running at 40-41. I think we’re struggling with the size of the injectors, we’ve got 650cfm on an N/A build, and the pulse width requested by the ECU is approaching the minimum pulse width of the injectors at low load/idle. We...

I’m nearing the end of a 2UZ-FE VVTi rebuild, Link ECU install and run-in, and running into some trouble figuring out the fuel delivery. Here’s the build: 10.5:1 compression, forged internals Kelford 208-B cams 650CFM Victory injectors (for flex fuel down the road) Deatschworks 255 Lph fuel...

One question: I want to rule out any kind of short in the circuit before adding anything. Is this a known issue when replacing 02 sensors? Or should I normally be able to unplug the o2 sensors and not have a significant power draw from trying to heat the old sensors? Thanks!

Since I don't need the heaters anymore (02 sensors replaced), would a resistor on each sensor circuit eliminate the problem?

I've installed a Link Storm ECU in piggyback position on a 2005 4Runner. I replaced the upstream 02 sensors with Wideband Lambda sensors, which are running on the CAN circuit, so the original upstream 02 connectors are consequently unplugged. Now I'm getting a parasitic draw that drains the...

Thank you for the follow up. I'm regrouping this week to figure out how far off I am from your model. I'll circle back when I have a few more answers. Thank you!

Hello! Help me Obi-wan, you're my only hope! :) Here's the current status. I'm still getting a couple of sensors to add in, and haven't gotten to first start (though I've watched a couple of your videos on things like priming the oil pump...) I am indeed adding wideband sensors. I did not...

Thank you, Ivan. Appreciate the feedback.

Really helpful--thank you! One remaining question--I'm replacing the stock injectors. Would you recommend running the stock injectors for that initial pre-tune run-in, or not worry about it? Thanks!

I've finally got my 4Runner motor back after dropping a valve on my rebuilt 2UZ. I did go with the heavier Kelford springs for the 208-B cams at Kelford's recommendation. I also added 650cc injectors and higher capacity fuel pump. I also added a Link G4X ecu and wired it in piggybacked with the...

Key question--I believe stock valve springs were used, not heavy springs. Would that contribute to the issue?

Here's the keeper that failed. Is this just a matter of switching to chromoly? Or does that just shift the pressure to the next weakest link? Thanks for your response!
