Re: Blacktop + Centrifugal Supercharger
Looks like they might be unwilling to play with USA people. I'll definitely reach out to them anyways, thanks!

Blacktop + Centrifugal Supercharger
I'm doing research into adding a centrifugal supercharger onto my 20v blacktop. I was very successful with my Link engine management swap and need to plan the next thing! I'm interested in the Rotrex C15-60, as the factory airflow of a blacktop at 8000rpm (on paper) really matches up well with the r...

Re: Getting stock tachometer to work with haltech ecu?
I did this with a Link ECU and an aw11 tachometer. Back emf is high voltage, and if you just look at the circuit board on the tachometer, there is a resistor first thing on the pin that gives tach signal to bring the signal down to the input voltage level of the chip that comes after. On my tach it ...

Re: Blacktop Torque Hole
Thanks for the reassurance! I'll try tinkering here and there with in-plenum stacks, maybe use this as an excuse to pick up a shiny new exhaust manifold...

Re: Blacktop Torque Hole
That's a phone dyno. http://tuning.perfexpert-app.com it's very consistent with itself, very low variance between runs on the same stretch of asphalt.

Blacktop Torque Hole
20v Blacktop in an 88 mr2 using factory mr2 trunk air intake, factory Blacktop exhaust manifold and sv3power 2-1 downpipe + exhaust. What I expect to see: Torque mostly trends up with rpm until some drop-off point up high. What I see: Torque drops out significantly 3250-4400rpm. What I've tried: * F...

Re: Blacktop Link G4+ ECU
ECU plugged in and works so far so good. * Fuel pump does a key-on 2 second cycle. * Water and air intake temp sensors read within a couple degrees of what weather.com says the temperature is. * TPS didn't work but then I plugged it back in and it worked fine. It was exciting seeing the throttle goi...

Made the patch harness today. It was more of a hassle than I anticipated; I'll find out soon if Link installed the factory smoke or not

Re: Blacktop Link G4+ ECU
Bold but respectable. I hope my skill is up to the task; I'm also not running a race engine though, so it's unlikely that my engine's ping events are quite as catastrophic as yours in case I do screw up momentarily. I'm considering setting up a 2nd VE and 2nd ignition map to toggle to when VVT is ac...

Re: Blacktop Link G4+ ECU
That's fair. I'm very focused on driveability, I'm sure I'll learn a lot over the coming months. As soon as I'm comfortable with the basic mechanics of tuning I'll rent a dyno. Want to have reasonable confidence that the time will add value. How do you deal with detonation, Matt? My Monsoon doesn't ...

Re: Blacktop Link G4+ ECU
Thanks Matt. I'll quit worrying about it for now. I accepted wiring it correctly as a precondition for the thing to work at all. :-) Do you just set up a static rule for VVT? Between x and y revs, and above z coolant temp? I had wanted to consider a throttle position vs rpm map as another input but ...

Re: Blacktop Link G4+ ECU
That's very interesting. Might need a scope finally! At any rate, if I get a weak signal, I'll do shielded wires first and rely heavily on hopes. Thanks for the terminology clarification, I'm definitely on the steep part of this learning curve. Just signed for my wideband and loom, one more package ...

Re: Blacktop Link G4+ ECU
You're the second person who I've interacted with who specifically mentioned AEM has trouble with these. I'm definitely steering clear of their hardware. Haltech seems to work on the 24t cas without fuss according to the guys at BGRS, and Link was recommended to me by a shop a couple hours up the in...

Blacktop Link G4+ ECU
Hi Club4ag! I have an MR2 with a healthy 4ag 20v BT. It's running on the factory BT ECU, vehicle wiring integration was done with a WireGap harness. I'm planning to swap in 1zz coil on plug. Have coils in hand, SQ Engineering bling for mounting is on the way. Have a CAN bus Bosch LSU 4.9 wideband in...
