Renix and Split second FTC1

Anyone have experience using the Split second FTC1 on a renix motor?
Im looking at MJs for a ford M90 project and the HO MJs are too rare and expensive.

Does the HO electronics have any performance advantage over renix? In other words given the same head, intake, exhaust, tb, ...ect, how would the performance compare?

Thanks, - Erik

I think the ChryCo ECU might dial back your mods a bit over time. I'm not sure, don't have first hand experience with those but on a RENIX I know mods hold if you mechanically tuned and tickle the computer right.

I don't know any solid facts about using standalone's yet. I've stepped back a bit waiting for a sure fire system to show up for myself as well. I would also like to run some boost too down the road. Bumpy
 
I think im going to use 30lb injectors, bump fuel pressure to 49psi, and use a GM 2 bar map. Ill install a Wideband and see how the renix responds AFR wise.

I might get away with this if I stay under 6 lbs of boost, run 93 oct. colder range smaller gap plugs, and maybe spray water meth.

If I can't get it to 12:1 ill likely order the psc1-02.
 
My reasoning is this:
With the stock 1 bar the pcm will read up to 0vac at 5v. So with the 2bar, instead of hitting positive pressure and the voltage not continuing to rise, it will continue to rise along with the positive pressure. I know it will be at a lower voltage and maybe half the fuel demand, but at least this way there is no "ceiling". Also ,we know the stock 1 bar acts up when it sees boost. The 2 bar should stay reading smooth.

A while back a guy on pirate 4x4 ran a turbo set up with just the gm 2 bar,injectors, and FPR on a obd1 for a while. I think it ran decent. He eventually switched to split second.

Remember this is a renix and I want to see what the afr looks like with 49 psi rail pressure and 30 lb injectors. I know we don't have as much experience with boosting the renix vs obd1 so it may not be as difficult to get a safe AFR. My hopes are it will work out to where it is not to rich under vacuum and just right at WOT. I have read a few people report this with the renix and boost.

I know this is not the right way to do it, but hell im on a budget and if the AFR is unsafe ill cough up the cash for split second.

Let me know what you think or if you have advise. It would be awesome if I could tune it mechanically but we all know how that can go.
 
Who was that? Ive read most of the threads. And yea it has happened to a couple of guys, one of them running 10:1 compression. But you can't deny people use things like RRFPR and MSDBTM with great success. Its not like you can't still get it to run pretty decent like that.
 
Hey, try it. It's the internet, no one can actually stop you from doing what you want. Be sure to post up the result.

My experience is all OBDII so I am no help anyway.
