Re: Classic Mini 5 port injection (siamese ports)

look here https://rovermems.com/ you can find some injector timing data here https://rovermems.com/discussion/mpi-injection-timing.html he even has some apps if you use the factory ECU. surely not as good as Rover Microcheck or Testbook, but it works. i've used the Android app with some cars https:/...

Re: Classic Mini 5 port injection (siamese ports)

just to be the pedantic Mini Driver, Rover engineers developed the Mini MPi in the early 90s. just to show it is superior to the SPi system taken from other Rover cars to push the car into tighter emission controlled times. but due to cost and maybe other reasons it was rejected. it was pulled out o...

Re: 1982 Chevrolet Corvette C3 Crossfire Injection TBI

my first reaction would be throw the CFI/TBI out and fit a TPI system from a later model. if you use something from the late 80s or early 90s even the TÜV may accept that for a historic vehicle. with that you can decide if you what to keep the batch/bank fire injection or to go all in with a fully s...

Re: 2000 Miata Turbo

I honestly HATE making AN lines, I can never get a good cut with whatever tool I use. I have a fine hacksaw which sort of works, my reciprocating saw works sometimes, and my angle grinder with a cutting disk is also iffy. ever tried a wood chisel? a sharp one with a good hammer blow will cut fast a...

IIRC he did, but gave full credit to the developer Not on opelgt forum. On opelgt he is now "developing" a new product which is not SECU and uses TunerStudio. yes, i've read that. but with speeduino he was reasonable fair and sold original PCB copies and his own designs based on that as s...

IIRC he did, but gave full credit to the developer. but other things were strange within that, like using some schematics (VR conditioner?) form others without mentioning, and a speeduino logo that looked very similar to the SECU one

Re: I don't want any trouble, BUT.

i have some hardware for Speeduino, basically at the same stage as my rusefi hardware so it "may run in a not to far away future". as a guess, rusefi will work before speeduino for me because it already has the trigger wheel decoder i need. i also try to play with FreeEMS and LibreEMS. som...

Andorra is the 5642/44 and the Mamba is the 5674, I don't think I've ever seen an Intel device in a Powertrain ECU. early Rover MEMS ECUs, made by Motorola, were using Intel CPUs, if that counts that counts :-) I just looked that up, the MGF used an Automotive qualified 87C processor.

there are some people around that do just that, using it like a water brake as used with hydraulic engine dynos.

with TBi there were 2 strategies over here to stop the injector, only has 1.3 ohm, from burning out. Bosch used a inline resistor fitted inside the ecu, Rover, with Motorola as ecu manufacturer, used PWM. but i think the LM1949 will be my choice, even if i won't use Jean's board. no need to have a P...
