Default Begi-s with MSPnP

Hey Everyone. instead of getting begi FMU i decided to upgrade to MSPnP. Now i have a couple questions. Ive read the Manual for the MSPnP and couple other how to threads. But i still have a few questions. I am going to run MSPnP with just the Begi-s kit. Nothing added to the car at all. Just the begi-s kit. Does anyone have a base map that i can start out with my set up? I pretty much need a map that is very safe for my Begi-s kit that i can drive on without blowing up my car.

Thanks, T

It is always a bit tricky when using someone's map. What year is your car? Auto or standard? Did you get an intercooler? Is everything stock:i.e. injectors, exhaust, etc...?

The base map that comes with the MSpnp will get you running, but you need to get to a dyno to tune your setup.

Hey! Thanks for replying :-)

Its a 1990 with no mods at all. Stock everything and begi-s kit with no intercooler and a smaller gt25 turbo. And its a 5 speed. Exhaust is a magnaflow unit and i am planning on removing the cat and putting in a test pipe.

MSPnP comes with a base map that's pretty conservative. Your car should start and run well enough so that you can tune your own map to your particular set-up.

I'm in the middle of that process myself. It would be nice to have a dyno, but there's a lot to be gained by driving and tuning on the fly. You'll need a laptop and a wideband O2 sensor and gauge, and lots of gas. A passenger who's good with computers is also helpful.

you can get a solid road tune, just listen for detonation with something like my detonation headphones. Everyone makes fun of them, but they work and I haven't blown up a motor. If you have EGT, then you can supposedly get your spark map pretty close to MBT if that's a possibility. To really fine-tune it though, you will need dyno time. I spent $200 and walked out with 80-more whp, and a safe tune that's ready for the track.

Fill out out location, and if you're local to me I'll help you get everything started.

Thanks for the replys guys. I live in Minnesota:-(. So whn I get the MSPnP I can just plug that in and drive ok on the map that Is preinstalled on it? By driving I mean able to get into a little bit of boost. I would love to learn how to tune myself. I know a little bit about running and pretty handy with computers. If I bring it to a tunner and have then tune my car as is and later I get an intercooler and bigger fuel pump how much will I need to change my tune to get more power with those two things. What will most likely have to be changed with an addition of a IC and a new pump?

You're teetering dangerously close on asking questions sooooo stupid that they get ignored...lol.

Look man, I've failed repeatedly at scoring books or data on "how to tune on a dyno," so I basically learned from reading here, and a few other things that I don't feel like searching for now. You can probably search for "tuning" and my user name and find an article on AFR tuning on the innovate forum and an article on spark/lpp/detonation/power from a hot-rod website. There are lots of little things that can make a big difference, but if you can understand the concepts of a safe AFR target like 11.5:1, and MBT without knock then you're half way there and way ahead of the curve. I've met a handful of "tuners" who are fucktard morons and I do not trust them with my car.

Yes, changing anything to do with the motor will change the VE and require additional tuning. I recommend you get everything together, in one shot, then take it to a tuner and cut a check if you're not ready to meet up with someone on this forum for tuning, or not willing to learn. If a tuner isn't willing to send you sample tables and datalogs of the tunes they've done (like a portfolio), then I'm not giving them my hard earned money. If you can't see examples of their work, then don't pay them. (a power and torque curve is insufficient justification for my money)

Knowing what I know now, I wouldn't pay anyone else to tune my car. This may be a case of luck with my current tune, or a case of the quote in my sig.

Thanks for the input. I know a good tuner in my area. Its just that i would love to learn how to tune myself. I am way batter at operate learning than learning from books. Show me how to do something and i will do it much better than if you give me a book to how to learn something. I will first try to see if there is anyone in my area who would be willing to show me how to tune and then if that does not work i will go and get it tuned by someone else.

hey everyone! I figured out how to use VE analyzer and tuned the VE tables a bit. I was wondering if i want to tinker with spark angle what should i look for. What is optimal spark angle?

Thanks, T

Optimal spark angle is tricky. For any given cell, it's the lowest angle that yields peak torque, for which you need a load-bearing dyno. In the higher cells, you are likely to encounter detonation before reaching peak torque, in which case optimum advance is a few degrees short of detonation.

If you do plan to actually tune for optimum spark in all boosted cells, be sure to bring a couple of spare engines with you when you show up at the dyno.

thanks for posting. i am going to eventually bring it to the dyno. i wont to tune it myself to be safe and still fast enough. I was looking at my logs and it looks my spark is around 19 to like 25 degrees does that sound normal or not. Does a bigger number mean more likely to detonate or the other way?

Considering your experience with tuning, I would not mess with your spark table at all. Just run the DIY table to be safe and tune VE. That's what I am doing right now. Yes, you can get more power from messing with the spark table, but to me it's not worth the risk unless you are experienced and have a good ear for detonation (or knocksense).
