Re: VVT control issues

Firstly, you need to accept that there will be a delay; cam actuators are a hydraulic flow based system, even if you went to 100% duty it'd still have a delay between target and actual. And good luck holding any angle other than minimum or maximum using such high dutys. You may be aware, but just in...

Re: MAF tuning discussion.

Sadly didn't help as the map delta finished just before the MAF spike even occured.. I'd probably need to set a generic timer based on map delta exceeding a threshold. Then I could taper the filter back down from 6 when steady state resumed. But 6 filter just caused too much of a lag and requires a ...

Re: MAF tuning discussion.

Wicked, that'll sort out the initial spike on opening. What would you suggest for the spike on throttle close. I was thinking about setting MAF filter against TPS derivative or hoping transient dis enrichment could at least stop the rich bump. - Also, while I'm asking advice but in a different direc...

Re: MAF tuning discussion.

I think the transient issue was because I had filtering at 6 (Testing the MAF spike reduction) Set it back to 2-3 and was much better, but now spikes have returned (Mostly noticeable when backing off the throttle) Yeah, did IPD vs MAF voltage to make scaling easier given it's buried in the settings ...

Re: map referenced regulator tune offset

I would personally think that the MAP would drop fairly quickly at the regulator.. They're not usually a large diameter or long hose to the regulator; especially given fuel flow is being held back, it'll want to pop the regulator open more very quickly. You're probably better off setting up your Tra...

Re: Spool asist boost

How much preload do you have on the actuator? Maybe try increasing the preload to improve response. Do note though, this can increase your boost levels elsewhere, so I'd suggest going to a zero duty to start with. I'm waiting for somebody to make a PWM or stepper linear actuator to replace the pneum...

MAF tuning discussion.

Any tips? I've only had experience with MAF tuning on OEM applications, everything else has been SD and Alpha-N. OEM they've done all the background stuff already for you. - Few things I noticed is that the Transient values need to be much more aggressive compared to SD (Presumably due to the lag ti...

Cruise control brake switch requirement.

Possible to make this settable to clutch or brake switch? I'd like to let the Haltech control my DBW and cruise, but I don't have enough inputs for a brake switch as well. I get that you have to have a safety net, but surely you could have the clutch be used to deactivate cruise just as the brake sw...

Dual boost control solenoids (open loop) question.

Question for people above my paygrade.. When using open loop boost control and only when you select dual boost solenoids, ESP lets you set negative boost control values in the base table (Which I'd presume starts to activate the decrease solenoid?) Problem is it doesn't appear to activate that solen...

Re: Tps, user demand?

You might be able to set the target idle RPM against a clutch or gear axis.. or even vehicle speed. So set the target idle control to 0RPM when gear = 1,2,3,4,5,6 and set target idle control to xRPM when gear 0 (Which i'd presume the ECU uses for neutral) From memory, gear goes back to neutral when ...

Idle control and/or ignition idle control?
That'd make it buck around.

Knock flash CEL tweak

Wouldn't mind being able to set a threshold at which it flashes the output light. Especially since the addition of timing restore, even the lightest of knock detection flashes the CEL. Personally I think it'd be a much more useful feature if you could set it up so it only occurs when the knock is X ...

Hold tight, dedicated Paddle Shift functionality is coming soon. sounds good. will this update be free? BR Great thing about Haltech is just about all their updates are free. It's a great way of keeping up with the competition, and shows how flexible their platform is. I think the only one (I presu...

Re: Automatic Long/short term trims.

If your axis are all the same in the base fuel and LTFT It's not much different to what you're talking about, just leave it be. The ECU still applies that correction factor over the base value. Base: (100) + LTFT: (+5%) isn't really any different to having the base cell = 105 from the get go. Ecu st...
