Can anyone help because my RB25 is free boosting, when i accelerate hard the BLITZ SBC eltronic boost controller seems to bleep and go read as is gones over safe boost, This is not the solinoid as i have already replaced it. I need help as im scared of blowing the HKS25/30. My actuator pipe is on. Though im having problems with my coil packs but under my understanding im sure that does not effect my boost at all. Not sure what to do because the car does not perform when its free boosting.

well if your gain setting is up to high your car will over boost, its a 1-100 setting, mine is set at 12-15 im not sure if aftermarket turbos can be set higher but have a play try setting at 15 and see if it still does it, not sure if you also know that when changing the setting the controller will take 3 or 4 learning runs before it sets itself so you will need to do 3 runs up to high revs see if it makes a difference anyway. do you have a manual for it because i can post one up for you. is it the id3 that you have?

yes try 15 the higher you go the faster boost will come on, so if you had it on something like 60 its going to boost spike, so try 15 and do 3 runs as it will be in learn mode for a few runs and see if it makes a difference, im looking for the manual for you at the moment.

      Surely the merged entity will be called "Honda" given the relative company values. I've got to be honest, I don't understand how merging 2 companies that missed EVs (despite Nissan making the first mass produced one) will solve their problems

      How "plug and play" is the Haltech Pro for R33 GTST

      By Murray_Calavera · Posted

      If you haven't bought the ECU yet, I would strongly consider buying a modern ECU. Yes it is very easy to setup and tune, however it is lacking many of the features of a modern ECU. The pro plug in is something like 10 or 12 years old now? Can't remember exactly but it is very dated now. In that time the Elite was released and now we have the Nexus platform.  I would strongly consider not buying the ECU that is 3 generations old now (especially as it isn't a cheap ECU!).

      Steps to DIY sanding car back ready for respray....

      Sorry I should have been more clear with the previous post.  The block is a sanding block - picture something like this https://motorguard.com/product/motor-guard-bgr161-bgr16-1-rigid-psa-sanding-block-2-5-8-x-16/ The guide coat is the paint It's two separate things I was talking about, there is no "block guide coat".

      Maybe more accurately, you aren't just dulling the existing paint, you are giving the new paint something to 'grab on to'. By sanding the existing paint, you're creating a bunch of pores for the new paint to hook on to.  You can lay new paint over existing paint without sanding it, might last a year or two then sad times. The paint will peal/flake off in huge chunks. By sanding it, the new paint is able to hang onto it and won't flake off.  Depends on the primer you are using. When you buy your paint, as the paint supplier what grit of sand paper to use before you lay down the primer.  Use whatever you like as a guide coat. Pick a colour that really stands out in contrast to the paint. So say your sanding/painting a currently white car, using a black guide coat would work well. You very lightly lay the black guide coat down, then as you sand the car with the large block, all the high spots and low spots will stand out as the black paint is sanded off (or isn't sanded off).  When you buy your paint, hit up your supplier for recommendations for what paint to use for a guide coat if you're unsure what would work well with your setup.
