post it up. im up for learning everything i can. so awesome, thank you.

found this old thread in the g4+ https://forums.linkecu.com/topic/6744-4age-20v-multi-condition-vvt/

im still waiting for 2 new wide bands in the mail. when u get that fuel table dialed in what do u do next? do i tune with vvt or without? how do i make a vvt table?

here is some tunes to give a better picture. im very new at this and really dont know what im doing. tune i went to the dyno with.pclx tuners map.pclx tuners map with duel fuel map attempt.pclx how do I use this fuel table?

we did get enough runs to find the best switch point to have the vvt on and off. i find the vvt is very inefficient at part throttle cruising. We also know how much fuel we need at wot from vvt on to off to the limiter.

7age 20v silvertop (stock cams), ls1 map, stock injectors, 11.2 compression, 1nzfe coils. hello i have a 7age 20v silvertop, i got the engine running and driving with 1nzfe coils. took the car to a tuner that does alot of hondas. we tuned the fueling with map and rpm. tuner was insistent that he tune with map only. he did well with the wot and we did some road tuning to get the cruising working well. big problem i noticed when i drove home was at highway speeds up hills the map was peaking out at 30% tps so there is a large rich area between 30 to 80 tps. i found out about alfa n tuning so i have been trying to road tune the part throttle using a duel fuel table set to overlay. i have no idea if this is the best solution or not. i also want to know if there is a way to fine tune the vvt like the picture. currently im using 2750 on, 6000 off and on at -0.2 mgp, all three conditions have to be met. really wish there could be a table used where tps and rpm could be plotted out like factory.

no injectors yet they are being cleaned but it fired right up on brake cleaner.

i unpinned the ground wire for coil one and put a new wire to the battery ground and ran a test and it works now. i think my problem was reusing the power and ground that went to the stock 20v coil is the problem. the ground wire must go threw the 20v ignitor and was keeping it working. even though if i had the ignitor pluged in and grounded to get 12v at the coil it still wouldn't fire. got some rewiring to do tonight.

wired in 1nzfe coils into pinout ports 7 8 17 20. i have 12.6v going into the coils. trigger scope shows a proper square wave but i get no spark during cranking or threw a spark test.

going to try those settings this week. car is on jack stands with a noisesy gearbox. time to pull it for the 7age. getting a e51 rebuilt for it. i have been very pleased on the power gains over the stock ecu.

I changed the ignition idle target to 25 degrees to get good idle at startup after 10 seconds it goes to its normal ignition of around 26 degrees. I wonder if this is a product of changing to a tps based ignition table.

A new problem I have found. The ignition angle is stuck at 10 degrees after startup for exactly 10 sec everytime the car is started.

Yes the log and scope were at idle. Going to try those settings tonight if I can get home at a decent time, been filling in for the painter at work thats on vacation. What do you mean by tracking?

oh thats nice. my silvertop is doing the same thing. hwat soaked iat sensor after a drive go to restart car it starts hard and wont idle for the first 15 secs.

here is a log and trigger scope TriggerScopeLog.llgx PC_Datalog_-_2021-08-10_84540_pm.llgx
