Hi, I looking for some advice. I've been chasing around this idle issue especially when conditions are hot (ie; stationary traffic) especially when AC is on. 1. My target idle tends to oscillates a bit 2. When in hot traffic and AC is on. When AC kicks in RPM would undershoot way below target badly and then recovers to target with AC step up after a while. But it happens the same when AC kicks off, RPM will undershoot below target before recovering to target as well. 3. If I try to overcome this by increasing base position or ac step up table, i will get high overshoots especially during situations when the car is moving and not under idle conditions. Such as coming down to a stop, decel and clutch in to neutral. It's on closed loop DBW. Appreciate the help and advice. Throttle is a bosch motorsports 68mm Link to the logs below OneDrive

Planning on setting up drive by wire soon on my version 4 STi(link g4x4x). I've noticed some kind of modification is required to allow DBW to work properly. Anyone know what is involved, and the procedure to get this done? Is it a software, a firmware, or a hardware charge? I'm almost positive I read this ecu was capable of DBW when I bought it. Guess I misunderstood..

Hi, I'm having some issues with DBW closed loop idle control. It's not happy with closed loop on. Open loop works fine, not perfect but okay. Wanted to try and run closed loop. As far as PID for the DBW, I think It's in reasonable range, and close to target. But could do better i think? Can I get some help on how I can make this work better? Current setup is Bosch Motorsport 68mm DBW, Mitsubishi 4G93 engine, Link FuryX. Here's the onedrive for the logs and tune. https://1drv.ms/u/s!Al7C1wyXCi4aqnBFnz3bmIYzeMDn?e=hIRxqA Thanks appreciate the help

Hi All, Currently running a bosch 68mm throttle body from a merc. And only recently it's been behaving erratic. TPS1&2 seems to fluctuate when there is no command (APS or AC/FAN stepups) example on idle. But under command it behaves fine when AC/FAN stepups are commanded. In the log DC motor seems to pulsate as well. Just wondering could this be a sign it's failing? Log and tune in OneDrive link as the file is too big to be attached. ECU is FuryX. https://1drv.ms/u/s!Al7C1wyXCi4aqiu-oHjrBU1OB5bd?e=M3nFtF

I would like to add a finger operated button launch control to my Toyota 2zz with Xtreme and drive by wire throttle. How do I wire this in? The car is used for targa rallies and we have multiple stop starts for passage controls, stop/go boxes per stage!! All help appreciated

Hello Guys, ECU Thunder, Evo 8 4g63 engine with DBW conversion (Evo X pedal + Bosch 68mm E-Throttle) I set the deadband to 0.0% (0.1% at idle is not acceptable ) The ecu can't reach the TP% requested.... For example... in the e-Throttle 1 table at 0% AP...i set 3% TP... Then idle position set to 0.3%... In some cases the ecu set TP to 3.4% (+0.1% that requested) other times 3.2% (-0.1% that requested) sometimes 3.3% (as requested) but need much time to reach that TP%... My dbw settings are : - P = 9 - I = 0.145 - D = 35 Any advice ? Thanks Regards

Hi there all, we would like to change the existing dbw to dbc. what do we need and how difficult is to run ? i know the parts that i want , the only thing is what should i do internally to the ecu. Thank you in advance Ted

Hi there, i would like to ask if anyone knows if a plug and play g4+ for a dbw can be altered to play cable throttle. it is for a subaru drag car that we have here and has the same as mine but we want to covert it to cable throttle for better response. Thank you in advance Ted

Got involved wit a LSX in a S13 drift car last week , when I tried to calibrate the TP i was getting the following fault code. Any thoughts/idea please

Hello everyone, I'm using i88 on single turbo 2jz with GM LS3 DBW TB and couldn't find the right balance with the E throttle setup.. I've tried the parameters that are written on specific e throttle applications section (GM TB) but still having issues with both calibration and idle.. My question is: does anybody have setup parameters for ACDelco 217-3153 GM LS3 DBW TB? Needed settings are: FrequencyDeadbandProportional GainIntegral GainDerivative GainMax ClampMin ClampThank you..
