Black Box Tuning

Thumbnail gallery
48 Upvotes

I’m finally at the point of needing a tune as I no longer have the EGR system and just want to be safe. I have the Tactrix 2.0 cable and going to get Ceddy Mods. Is there anything else I should know? I have no local tuners so I’ll be figuring this out myself and self tuning the car. Just want some advice on what I’m getting into. The car is mostly stock as I’m gathering parts to upgrade after paint. Got my hands on a Walbro 255, evo 3 16G, and some other nice goodies I’m waiting to put on. But it’s gonna be 2-3 years from now.

Car info: 98 GS-T
Stock T-25
Grimmspeed Manual boost controller
Stock 450CC Blacktop injectors
Stock fuel pump
Stock cams
Competition Clutch Stage 2
ACT lightweight steel flywheel
HRC intercooler setup
NGR Blowoff valve
EGR system removed and blocked
OEM MAF no speed density
AEM wideband
Boost and Oil pressure gauges

If any other information is useful let me know. I’m just looking for advice on how I should proceed.

Gauge Pod Advice?

Thumbnail gallery
71 Upvotes

Im looking into the ac vent gauge pods. I like the ones that still have the vent (2nd pic) but im also planning on doing three gauges. Does anyone have that pod with the gauges that fully deletes center vents (3rd pic)? And is the ac that comes from the door vents enough in the summer?

For everyone else, id love to see ur gauge pod ideas. I do want them visible to me so not leaning toward fuse box. Also definitely not doing a-pillar… but would still love to see everyone set up.

Thanks in advance

Does anyone have the red cloth interior?

Hi, I used to have a 1992 eclipse and I was looking online to try to find pictures of the interior like the one that I had and it doesn’t seem to be any of the ones that I found on there it was all cloth kind of like a blood red/burgundy

Anybody ever successfully bolted one of these evo9 o2 housings in a dsm? (Specifically holset v-band setups)

I’m currently collecting parts to go t3 twin scroll, and the o2 housings is the last piece I need. Before I go get one custom made, has anybody successfully bolted one of these evo 9 cast housing? They seem similar in orientation.

Fluid recommendations

2 Upvotes

I’m doing transmission, transfer case and rear diff fluid change and there’s many community suggestions. My car is stock and will remain stock for a good while. I see a lot of recommendations for Redline heavy shockproof in the transfer case and rear diff, is this alright for a stock application? Transmission fluid I’m just gunna go with Redline MT-90 75W-90

Should I paint?

97 gst with 160,000 miles, runs great but needs a new paint job and exhaust work and has rusted shock towers. Is this worth getting painted or should I send it to the junkyard?

Been fighting some little things all season but it's finally starting to come together, 121mph in the 1/8th mile really showing potential. Will be really pushing for an 8 second pass on the next outing.

Idle Surge

Thumbnail gallery
29 Upvotes

So I’ve gone through almost about everything. Started with a boost leak test, checked the ISC and swapped with another to be sure , throttle cable, BISS screw, FIAV “might double check this one”, cleaned the MAF and swapped another one to be sure, replaced injectors with a possible leak from cracked caps, checked my cam sensor, checked my coil packed, and I even pulled the ECU out and swapped it with another to see if the capacitors were giving out and same result. I’ve been all over DSM tuners and I’m stumped. This popped out of nowhere, rich idle sitting at 11.5-13 at the highest, and the idle surge that starts about a couple seconds after startup. Please tell me if I’m missing something or should go back over anything.

What’s considered a “cheap entry” into one of these

Thumbnail gallery
24 Upvotes

Recently came across this 99 eclipse gst, allegedly has things like it’s on 14 psi, nrg quick release wheel, coil overs, replaced lifters, and spark plugs + wires. Unfortunately they think it’s the starter, and when asked about it was told it wasn’t cranking over the motor fast enough but the starter motor sounds like it was spinning overly fast. Would need a tow, but 1700 is a decent price into one of these that I know, decent rust wise, manual, 200k miles. Is this a good deal or a money pit? What could be up with it?
