I only setup the 90-93 ECUs for sequential if the owner asks for it, as it requires additional wiring.

freedomgli 10-23-2014 10:27 AM

Gotcha. Thanks. Pretty sure mine has the wires needed to make sequential fuel injection work, just not sure about the jumpers inside.

when is this bad boy going to hit the dyno??? hurry it up JOSH/RYAN!!!!

emilio700 10-23-2014 12:57 PM

I predict 144whp/126tq on pump gas, Dynojet. +5% for E85

curly 10-23-2014 01:05 PM

Whoa! I'd love to see those numbers. We are dyno'ing with a Dynojet at English Racing. We're hoping the shaved head, sequential injection, 949's intake, and some dyno tuning will bring us close to those numbers.

As to when, hopefully soon. Ryan's doing the 24hr chump race at PIR this weekend, then we'll start planning a date.

With NB2 injectors, a stock '90 FPR & FP, are we able to run E85? 151hp/132ft/lbs would be awesome.

Need moar FPR. Find an OEM NB in tank regulator (60psi). Bolts right onto the fuel rail. Otherwise, yeah.

Like the MSM one I have sitting in my garage? Just looked at it. Looks easy enough, but there's no vacuum reference?

greddygalant 10-23-2014 02:35 PM

that would be amazing, although the biggest issue is the limited number of e85 station in portland, plenty across the river in WA though. Ideally youd have two maps, I imagine with the ms3 map switching shouldnt be too difficult, and all youd need is load up on 5 gallon jugs of e85 before hitting the track. English Racing also has a bunch of E85 so thats always an option. I say go for it, Im considering it for both of my cars at this point as well.

curly 10-23-2014 06:27 PM

Yeah one of the db37 needs to be momentarily jumped to ground I believe and itll switch maps. Or something like that. Need to hook up on board data logging too. And launch. Dunno where Ryan is planning on putting all the switches.

No big red NOS button. :(

^^^ I love that steering wheel/dash setup, I just wish the owner had installed an aftermarket airbag steering wheel for safety.

Reverant 10-26-2014 07:38 AM

The car has OMP HTE seats and OMP 6-point 3" harnesses.

Are you for real right now?

oregonmon 10-27-2014 12:31 PM

Driving around early this morning I noticed headlights and dash lights dimming/brightening/flickering. This happened under steady throttle and idle. We'll take a look today for the cause. It also wants to idle at about 2200rpms when cold.

curly 10-27-2014 01:07 PM

Fairly certain something funky is happening with the alternator for the lights to be flickering, and the 2200rpm idle is just Idle Cranking Duty/Steps. I think.

Reverant 10-27-2014 03:32 PM

You are still using the 90 alternator, right?
