ok so i have a d15b7 with a z6 head running a chipped p28. and i have a full greddy kit sitting down stairs, mom says i need to clean up space so if i got a turbo base map chip and kept it on like 4lbs would i be fine without a tune? i have 440cc injectors also.

No, you will need a tune.

Posting a question like this will get you no where around here lol.

Some people run up to 10PSI on stock ignition timing on D series. I tried that once and lifted the head.

Get a basemap for your 440CC injectors and conservative timing. I would run 8-10PSI on your setup with a retard rate of 1.20 Degrees per PSI of boost. I know those greddy kits come with little 16G style turbos and spool rather quickly. I would also get a wideband and make sure youre 11.9AFR MAX in boost. Any learner and I would get it reburnt.

4PSI will be useless IMHO.

i know it will be useless but i have to make space in my garage, so i could run 7lbs and retard 7 degrees of timing with a base map for my 440ccs and i would be ok? itll get tuned later i just blew all my money on the car, needed alot of **** lol, got the kit for almost free.

You don't need to retard timing. Contact Xenocron, get them to cut a basemap chip for you for 7PSI - that's the stock wastegate on the Greddy kit. Ideally you should get it tuned, but Xenocron's basemap will definitely get you by.

its internally wastegated and i had to rotate it to get the turbo to fit on manifold, how do i set boost with a waste gate? and is there anyway i can make a custom mount for it?

A basemap is what retards the timing when entering boost. As the MAP sensor reads positive pressure it will lower (retard) the timing usually based on a per LB of boost basis.

What do you mean by rotate it? Does the rod still line up with the flapper on the housing? There is a spring inside that round looking thing (wastegate) that will open at a certain PSI. (Probably around 7PSI) to run more boost then what it is made for you would use a boost controller. You cannot lower the boost anymore then it comes with. So if you go hit boost with just a vacuum line attached from turbo to it and it opens at 9PSI, you can't go any lower then 9 without changing the wastegate or porting the housing.

If you're not flying around in boost very often, I see no reason why a basemap wouldn't last a little while. The wideband+keeping it rich is a good idea. If you go that far, maybe look at a RTP and just slowly street tune it to keep you safe.

civicb1812345

ok so a basemap, and if i got something like a 4 pin datalogging cable and a cable with chrome could i still street tune it? ive heard rtp is exspensive... and no the wastegate dont line up with the flapper anymore, and the rod is ajustable i just looked it up they said short is less longer is more. so ill make it hella short then slowly turn it up to 7psi. i already have a boost gauge installed(no vaccum hose, which i dont know how to hook up). i already have an sst reburnable chip also

civicb1812345

and i dont have the money for a wideband, unless i can find a used one.

Sell the kit. Someone will scoop it up. You can't street tune without a wideband unless you have a magic sniffer that can calculate AFRs accurately. To street tune, basically, you need the wideband and datalogging. You make slow broad adjustments to dial in the AFRs while using degree per lb ignition retard. The wideband is a necessity.

civicb1812345

alright ill pick up a wide band and a datalogging cable. best free software to use? i was just gonna use chrome

Best and free don't really exist in the same sentence.. But good luck with it either way

civicb1812345

so chrome is ight?

Not generally, but I have seen plenty of good chrome tunes. Maybe not the best, but they can be safe.

It's a lot to jump into though. I don't know of any good free datalogging software. Everything I try sucks. But maybe that's just me.

civicb1812345

ive download a map for a d16z6 on 8 lbs with a t25 and 450cc injectors, all the same as me sept im running a b7/z6 mini me. think this will be alright till i can afford neptune/demon combo?

4genaccordfreak

I would suggest not doing anything unless you can "afford" to do it right the first time. Unless you enjoy learning lessons the hard/expensive way, then by-all-means do what you want. This whole thread is filled with I want to do this, I want to do that, but I have no money to do this and no money to do that.

All this because your mom told you to clean up your junk in the garage.

Wow.........

civicb1812345

ive got the money to dio it right just wanting to know if its possible to get by on less, as im not running high boost or power, i have ordered a lc1 wideband, so ill know my afrs, and i have a chipped p28 with a 4 pin cn2 data logging cable.

A little harsh.

HondaTech, as a community, has a very set mind. If you want to honestly talk to anyone who will humor your idea of using someone else's map and just 'watching' your AFRs, go to pgmfi.org.

More on topic. Low boost and low PSI doesn't mean you can't smoke some rings or throw a rod. It's a D-series motor, no offense to anyone, but they don't handle a whole lot of boost stock. It's also a D15 block. Not sure what your compression ratio is, but I would be careful none the less.

Be careful if you want to do it, then do it. Don't come to a website like this looking for approval.
