Im new, a few questions

[rush6432]

Hey guys, im new to the Sy/Ty world. always been a fan of these vehicles, just never had the cash to own one. Finally got mine today, 91 Syclone with supposedly a quite a bit done to it. i dont know if the previous owner is on here or not, if anything i type is incorrect (Fact wise) please correct me, im very eager to learn more about these vehicles. Like i said ive got a 91 Syclone (stripped and repainted red then re-assembled) Car has unknown size turbo on it. doesn't appear to be stock but i could be wrong. i THINK (from ive been told) the stocker is a mitsu 17c? anyway, car supposedly has eagle rods, j.e pistons, arp studs all around, vortec heads, kenne bell fmic, kenne bell intake and headers with deltagate, J & S/Kenny Bell knock sensor/dentination retard electronic computer, with a/f and knock indicators. Trans is rebuilt supposedly with 2800 stall (kenne bell unit??) currently i CANNOT go w.o.t, i get to about 18 psi (modulating throttle) and anything past it shows knock and gets lean on the af indicator. Im not new to the boost/tuning world, but i am new to the domestic motors and boosting. im not a n00b when it comes to cars. i just dont know anything yet about tuning with these vehicles or how you go about re-tuning them. Ive been a mitsubishi guy for a while (done 3000GTs/Stealths, Eclipses, lil on starions. Anyway Truck came with 2 chips, current one installed is set for pump gas (93) or maybe 98 octane (not sure) second is a race gas chip. again if anyone can point me in the right direction on info/tuning and such on these cars and what to watch for. Any help would be appreciated.

pics below of new truck and my previous project.

And my previous project, 3000gt SL, FWD (crappy drivetrain i know) 10:1 Compression single turbo, T04R with .81 a/r. (basically T67) kit was custom one off made by myself and help from a friend with welding a few things (i cant weld for shit)

Re: Im new, a few questions

well idk what type of turbo that so I cant help you there maybe if you take a few close up pics you may get a better answer. As far as the chip goes if its kenne bell's get rid of it!!!! I think many people refer to it as the kb kaboom chip. its no good. I could be wrong though but thats what ive read. jsm has made a coupl of good threads on boost/fuel tuning for our trucks and just read as much as you can in the chipping/tuning forums. since your not new to cars/tuning you should pic it up quick. Check around on the boards you should be able to find some other sy/ty member's in your area that could help you out too. sounds lik a nice build and looks like a good truck. good luck with it! :tup:

why the gn mats?

Re: Im new, a few questions

why the gn mats?

lol good question. dunno, thats how i got it.

i may try changing the wastegate spring out today with some others i have sitting around, hopefully it will allow me to drop the boost lower so i can stay around 15 -17 psi (where it doesn't knock)

Re: Im new, a few questions

Turn that wastegate rod in enough to where you're only at like 15-16 psi. If you don't have an aftermarket gauge, then just go by that knock light.

Re: Im new, a few questions

do you have datamaster?

Re: Im new, a few questions

do you have datamaster?

nope sure dont. from what i gathered i think i have kenne bell everything.... fmic with pipes, intake, headers, knock retards sys (j&s) possibly turbo. its externally gated with a turbonetics delta gate but seems like its either hooked up wrong to an mbc or its just got too high of a spring. from what i gathered i hve a 7th injector but wiring goes no where and same with ss line that feeds the injector into the intercooler pipe before t-body. im gonna grab a hobbs pressure switch and hook the injector up and set it to come on right before it starts to get lean. what is datamaster?

Re: Im new, a few questions

7th injector is a waste of time. datamaster is a tool to read what your engine is doing in situations, i.e. idle, cruise, under load, wot.

Re: Im new, a few questions

Nice, is that the salvage title truck from houston/pearland/alvin/somewhere over there?

It was on craigslist a while back, wife wouldn't even let me go and look at it.

well i agree, but its what ive got to work with right now. datamaster just plugs into aldl port? like a datalogger??? can it read knock sensor?timing? narrowband o2 sensor voltage? if so then ill def pick on up, im used to tuning via knock and timing on a datalogger. just need somthing to control fuel with and timing. anyone got somthing they can suggest? piggyback? dont like the chip shit. also if anyone has a stock chip let me know, id like to sell or get rid of these kenne bell chips ive got.

Re: Im new, a few questions

yes datamster is a datalogger. you will have to change fuel and timing manually

Re: Im new, a few questions

Actually spoke to the guy you bought it from, and he scared me away... he really didnt seem to know much about anything on the truck, and had told me Id need to bring a battery to look at it because he had robbed the battery out of the Sy for his tow truck.... So I hope you got a good deal, and other than the seller, it was really an intriguing truck... Hope it all works out, and if it does, it will be fast!! Hang in there... this forum is a wealth of info, and youll get the answers you need right here... Mike

Re: Im new, a few questions

the knock/lean issue sounds like a fueling issue, either you've run out of injector or fuel pump or fuel pressure is too low. if it's a stock pump and injectors you're probably need to upgrade. a good baseline is an ultimate chip w/ 50lb injectors and a walbro 255.

well from what ive gathered i THINK it has stock injectors.... but it has an inline fuel pump thats REALLY goddamn big and makes an annoying whinning noise (more so than the walbro 255s) im pretty sure i have enough pump but not injector wise. what SHOULD the fuel pressure be at idle??
